Word Problems on Addition and Subtraction of Decimals

Read the questions given in the word problems on addition and subtraction of decimals to do the needful as required. We know we need to add or subtract the decimals as we add or subtract ordinary numbers.

Let us consider some of the following examples.

1. Kate had $ 368.29. Her mother gave her $ 253.46 and her sister gave her $ 57.39. How much money does she has now?

Money Kate had                                        =             $ 368.29

Money gave her mother                              =             $ 253.46

Money gave her sister                                =         +   $   57.39

Total money she has now                            =             $ 679.14

2. Maria had $ 469.38. She gave $ 99.37 to Mike and $ 124.93 to Kerry. How much money is left with her?

The amount given to Mike                =             $  99.37

The amount given to Kerry               =        +   $ 124.93

Total amount given                         =             $ 224.30

The amount Maria had                     =             $ 469.38

The amount she gave                      =        -    $ 224.30

The amount left with Maria               =             $ 245.08

3. The sum of three decimals is 496.28. Two decimals are 238.94 and 110.09. Find the third decimal.

One decimal                                       =             238.94

Another decimal                                  =        +   110.09

• Addition And Subtraction In Decimals

Addition and Subtraction of Decimals

Addition and subtraction of decimals  are a bit complex as compared to performing the operations on natural numbers. Before we learn how to add or subtract any two or more than two given decimals, first, let us understand decimals. The decimal number is used to represent a number with greater precision than integers or whole numbers. It uses a dot in between numbers, which is said to be a decimal point. Decimals are nothing but the simplified version of fractions. Check problems based on  decimal fractions  here.

For example, when we have to divide three pies among 4 kids, we cannot represent the pies received by each kid in terms of integers alone, as each kid has received pies that lie between 0 and 1. To deal with other similar problems, the concept of decimal was introduced. Thus, the idea of addition, multiplication, division and subtraction of decimals is an important topic. Let us say two friends are contributing to buy a cricket ball that costs Rs. 20. One of them has Rs. 7.50, and the other has Rs. 18.50. To know how much money each will have to contribute and how much they will be left with, they must understand the concept of addition and subtraction of decimals.

Addition of Decimals

As we know numbers can be added, subtracted, multiplied and divided. However, all these type of operations can be easily performed on natural numbers. In case of decimals, addition can be done in a specific way. The addition of decimals involves several steps. 

How to Add Decimals?

Addition of decimals is performed using the following steps:

Step 1: The numbers are first padded with zero depending upon the maximum digits present after the decimal for any of the numbers. 

For example, while adding 3.456 to 7.1, since the number 3.456 has the number of digits after the decimal, the padding is done according to 3.456. Since 3.456 has 3 digits after the decimal, we pad two zeros after 1. So, 7.1 to three places is 7.100.

Step 2: The numbers are lined up vertically along with each other as given in the below figure.

Step 3: Finally, add the decimal numbers similar to integers and place the decimal point accordingly.

Let us understand the concept more clearly with the help of the following examples:

Also, read:

Examples of Decimal Addition

Let us see some examples of adding decimals.

Example 1: Addition 1.091 + 1.33.

Example 2: Addition 0.0075 + 5.

Example 3: Add 9.1, 3.22, and 0.66.

Given, 9.1, 3.22 and 0.66.

As we can see, 9.1 has only one digit after the decimal but 3.22 and 0.66 have two digits.

Hence, we can write 9.1 as 9.10

Now add all the three decimals.

Subtraction of decimals

Subtraction of decimals involves the subtraction of the decimal number with a small whole number part from the decimal number with a greater whole number part. However, we need to follow certain rules while performing the subtraction on decimals.

How to Subtract Decimals?

Subtraction of decimals is performed using the following steps:

For example, while subtracting 3.456 from 7.1, since the number 3.456 has more digits after the decimal, the padding is done according to 3.456. Since 3.456 has 3 digits after the decimal, we pad 7.1 to three places as 7.100.

Step 2: The numbers are lined up vertically along with each other as shown below.

Step 3: Finally, subtract the decimal numbers similar to integers and place the decimal point accordingly.

Examples on Decimal Subtraction

Example 1: Subtraction: 7.304 – 1.15

Example 2: Subtraction 4.1 – 0.94

Adding Decimals Lesson

Example 1: Add: 52.3 + 973.41

Analysis: Let’s use our knowledge of mixed numbers to help us analyze this problem.

Recall that a decimal number can have a whole-number part and a fractional part. When adding decimals, you must first   line up all the decimal points in a column . Lining up the decimal points ensures that each digit is in the proper place-value position. Once each digit is in the proper place-value position, the whole-number parts are lined up with each other, and the fractional parts are lined up with each other. This is shown in the table below.

Now that we have lined up the decimal points, you will notice that the numbers being added do not have the same number of decimal digits. Let’s look at this problem on paper without a place-value chart.

      52.3 +  973.41

You can write an extra zero to the right of the last digit of the first decimal so that both decimals have the same number of decimal digits.

      52.3 0 +  973.41

Just as with whole numbers, start on the right, and add each column in turn. Note that you are adding digits in the same place-value position.

      52.3 0 +  973.41   1025 . 71

• Place the decimal point in the sum.

      52.3 0 +  973.41   1025.71

Answer: The sum of 52.3 and 973.41 is 1025.71.

Example 2: Add: 0.078 + 3.09 + 0.6

    0.078     3.09 0 +  0.6 00

Analysis: If you need to carry (i.e. if a columns adds up to more than 9), remember to add the tens digit of that column to the next column.

         1     0.078     3.09 0 +  0.6 00     3.768

Answer: The sum of 0.078 and 3.09 and 0.6 is 3.768.

Analysis: Each of these numbers represents money; however, the second is written as a whole number. Change the second number so that it has two decimal digits, and then perform the addition.

   $  77.23 + $  88. 00    $165.23

Answer: The sum of $77.23 and $88 is $165.23.

• Line up all the decimal points in a column.
• When needed, write one or more extra zeros to the right so that both decimals have the same number of decimal digits.
• Start on the right, and add each column in turn. (Add digits in the same place-value position.)
• If you need to carry, remember to add the tens digit of that column to the next column.

Example 4: Add: 28.5 + 34.5

Analysis: You will need to carry more than once. Accordingly, the addition will be divided into three steps to show the process of carrying.

Answer: The sum of 28.5 and 34.5 is 63.

Example 5: Add: 3.986 + 37 + 25.902

Answer: The sum of 28.5 and 34.5 is 66.888.

Example 6: Add: $12.95 + $67.89 + $54.55

Answer: The sum of $12.95 and $67.89 and $54.55 is $135.39.

Answer: The sum of 5.8794 cm and 7.48 cm is 13.3594 cm.

Summary: When adding decimals, you must first line up all the decimal points in a column. Lining up the decimal points ensures that each digit is in the proper place-value position. You can then add digits in the same place-value position to find the sum.

How to Perform Operations of Decimals: Word Problems

Greetings, budding mathematicians! Today, we're going to jump into an adventure with decimals. Working with decimals is a fundamental math skill that you'll use in many aspects of life, from managing money to measuring distances.

Introduction to Decimal Operations

First things first, let’s talk about decimals. A decimal is a way of representing a number that’s less than one, or a number that’s a whole and a fraction together. When you work with decimals, the same rules apply as when you’re working with whole numbers, but the decimal point plays a crucial role.

There are four major operations that you can perform on decimals:

• Subtraction
• Multiplication

Now, let’s tackle some word problems involving decimal operations.

Step-By-Step Guide to Solving Word Problems with Decimal Operations

Step 1: understand the problem.

First and foremost, carefully read through the problem. Identify what you know and what you need to find out.

Step 2: Plan the Solution

Next, decide which operation (addition, subtraction, multiplication, or division) will help you solve the problem. This will depend on what the problem is asking.

Step 3: Carry Out the Operation

Perform the operation on the decimals. Remember to align the decimal points when you’re adding or subtracting, and apply the rules for multiplication and division of decimals correctly.

Step 4: Check the Answer

Finally, check if your answer makes sense in the context of the problem.

Consider this problem: Laura bought \(2.3\) kilograms of apples and \(1.5\) kilograms of grapes. How many kilograms of fruit did she buy in total?

Step 1: Understand that you know the weight of apples and grapes separately, and you need to find the total weight.

Step 2: Realize that to find the total, you need to add the weights together.

Step 3: Add the weights: \(2.3\ kg + 1.5\ kg = 3.8\ kg\).

Step 4: Check that the answer makes sense. Laura bought \(2.3\ kg\) of apples and \(1.5\ kg\) of grapes, so it makes sense that she bought \(3.8\ kg\) in total.

Keep practicing with different word problems, and you’ll get the hang of decimal operations in no time. Remember, the more you practice, the better you’ll get. Happy calculating!

Adding decimals

Here you will learn about adding decimals including how to add decimals with models and with the standard algorithm.

Students will first learn about adding decimals as part of numbers and operations in base 10 in 5th grade. They will build on this knowledge and use the standard algorithm to add as a part of the number system in 6th grade.

What is adding decimals?

Adding decimals is when you add numbers involving decimals.

Let’s look at the strategies for adding decimals.

Common Core State Standards

How does this relate to 5th grade math and 6th grade math?

• Grade 5 – Numbers and Operations in Base 10 (5.NBT.B.7) Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
• Grade 6 – The Number System (6.NS.B.3) Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.

How to add decimals

In order to add decimals with models:

Show each number using decimal models.

Combine each place value.

Write your final answer with the decimal point.

In order to add decimals with the algorithm:

Stack the numbers and line up the decimal points (and place value).

Add each column from right to left and regroup the numbers when necessary.

Write your final answer with the decimal point and check to make sure your answer is reasonable.

[FREE] Adding Decimals Worksheets (Grade 5 to 6)

Use this worksheet to check your grade 5 to 6 students’ understanding of adding decimals. 15 questions with answers to identify areas of strength and support!

Adding decimals examples

Example 1: adding decimals with models.

Solve 3.5 + 4.9 = \; ?

2 Combine each place value.

3 ones + \; 4 ones = 7 ones

5 tenths + \; 9 tenths = \; 14 tenths

3 Write your final answer with the decimal point.

Example 2: adding decimals with models

Solve 1.12 + 2.3 = \; ?

1 one + \; 2 ones = \; 3 ones

1 tenth + \; 3 tenths = \; 4 tenths

2 hundredths

Example 3: adding numbers with one decimal place

Solve 5.8 + 3.7 = \; ?

The answer is 9.5.

Is this answer reasonable? Use rounding to estimate a reasonable answer.

For smaller numbers, you can round to the nearest ones:

5.8 rounds to 6

3.7 rounds to 4

The sum should be close to 10. Since 9.5 is close, it is a reasonable answer.

Example 4: adding numbers with two decimal places

Solve 9.18 + 7.35 = \; ?

The answer is 16.53.

9.18 rounds to 9

7.35 rounds to 7

The sum should be close to 16. Since 16.53 is close, it is a reasonable answer.

Example 5: adding more than two decimal numbers

Solve 3.79 + 2.18 + 14.6 = \; ?

A zero can be added to 14.6 as a placeholder. It does not change the value because 14.6 = 14.60.

The answer is 20.57.

3.79 rounds to 4

2.18 rounds to 2

14.6 rounds to 15

4 + 2 + 15 = 21

The sum should be close to 21. Since 20.57 is close, it is a reasonable answer.

Example 6: adding more than two decimal numbers

Solve 34.3 + 22.91 + 56.07 = \; ?

A zero can be added to 34.3 as a placeholder. It does not change the value because 34.3 = 34.30.

The answer is 113.28.

For larger numbers, you can round to the nearest tens:

34.3 rounds to 30

22.91 rounds to 20

56.07 rounds to 60

30 + 20 + 60 = 110

The sum should be close to 110. Since 113.28 is close, it is a reasonable answer.

Teaching tips for adding decimals

• Decimal work in 4th grade centers around understanding through models, particularly area models, number lines and connections to fractions with the denominators 10 and 100. To build on this in 5th grade and 6th grade, always have physical or digital models available for students to use when necessary.
• To introduce this topic, give students a decimal addition problem and give them time to solve in a way that makes sense to them. Then go over the different solving strategies as a whole group.
• In the beginning, you may want to stick to smaller decimals or problems that do not involve regrouping. However, at some point it is important to transition to showing students all kinds of decimal addition problems mixed together. This gives them an opportunity to identify which solving strategy to use.
• Math worksheets may have their place when students are still developing understanding around decimal addition, but once students have a successful strategy and can flexibly operate, incorporate math games or real-life projects that involve addition of decimals.

Write your final answer with a decimal point.

You can also solve with the algorithm by lining up the decimal points and adding each column.

2. Solve 2.84 + 6.19 = \; ?

2 ones + \; 6 ones = \; 8 ones

84 hundredths + \; 19 hundredths = \; 103 hundredths

3. Solve 0.069 + 5.987 = \; ?

You can solve with the algorithm by lining up the decimal points and adding each column. Regroup the numbers when necessary.

Is this answer reasonable? Use rounding to estimate a reasonable answer. For smaller numbers, you can round to the nearest tenths:

0.069 rounds to 0.1

5.987 rounds to 6

The sum should be close to 6.1. Since 6.056 is close, it is a reasonable answer.

4. Solve 2.1 + 3.87 = \; ?

You can solve with the algorithm by lining up the decimal points and adding each column.

A zero can be added to 2.1 as a placeholder. It does not change the value because 2.1 = 2.10.

Is this answer reasonable? Use rounding to estimate a reasonable answer. For smaller numbers, you can round to the nearest ones:

2.1 rounds to 2

3.87 rounds to 4

The sum should be close to 6. Since 5.97 is close, it is a reasonable answer.

5. Solve 9.04 + 17.381 = \; ?

A zero can be added to 9.04 as a placeholder. It does not change the value because 9.04 = 9.040.

9.04 rounds to 9

17.381 rounds to 17

The sum should be close to 26. Since 26.421 is close, it is a reasonable answer.

6. Solve 20.3 + 13.67 + 0.998 = \; ?

Zeros can be added to 20.3 and 13.67 as placeholders. It does not change the value because 20.3 = 20.300 and 13.67 = 13.670.

20.3 rounds to 20

13.67 rounds to 14

0.998 rounds to 1

The sum should be close to 35. Since 34.968 is close, it is a reasonable answer.

Adding decimals FAQs

Yes, you follow the same steps to subtract decimals. The only difference is that you subtract each place value position instead of adding.

No, these strategies will also work when adding whole numbers and numbers with decimals.

Following the Common Core recommendations, in 5th grade, students should work with tenths place, hundredths place and thousandths place. In 6th grade this is expanded to smaller numbers. Check your state’s specific standards for further clarification.

Adding and Subtracting Decimals

Adding decimals is easy when you keep your work neat

To add decimals, follow these steps:

• Write down the numbers, one under the other, with the decimal points lined up
• Put in zeros so the numbers have the same length ( see below for why that is OK)
• Then add , using column addition , remembering to put the decimal point in the answer

Example: Add 1.452 to 1.3

Example: Add 3.25, 0.075 and 5

That's all there is to it: line up the decimal points, pad with zeros, then add normally.

Subtracting

To subtract, follow the same method: line up the decimal points, then subtract .

Example: What is 7.368 − 1.15 ?

To check we can add the answer to the number subtracted:

Example: Check that 7.368 minus 1.15 equals 6.218

Let us try adding 6.218 to 1.15

It matches the number we started with, so it checks out.

Putting In Zeros

Why can we put in extra zeros?

A zero is really saying "there is no value at this decimal place".

• In a number like 10, the zero is saying "no ones"
• In a number like 2.50 the zero is saying "no hundredths"

So it is safe to take a number like 2.5 and make it 2.50 or 2.500 etc

But DON'T take 2.5 and make it 20.5, that is plain wrong.

Adding Decimals

Adding decimals means finding the sum of two or more decimal numbers. Although adding decimals is similar to the regular addition of whole numbers, there are certain rules that need to be followed while adding them. Let us learn more about adding decimals, their rules, along with examples.

How to Add Decimals?

Adding decimals is similar to the usual addition of whole numbers. We know that a decimal number is a number with a whole number part and a fractional part which is separated by a decimal point. However, this does not change the rules for the addition of decimal numbers. For this, we need to align the decimal numbers according to their place values one below the other, keeping the decimal point intact, and then add the numbers. We should remember that the decimal place value chart has some extra place values, like, the place value just after the decimal point is called tenths, followed by hundredths, thousandths and so on.

Rules for Adding Decimals

While adding decimals, we need to remember some rules that would be helpful and make the addition easier.

• Align the decimal numbers in such a way that they are placed in the correct place according to their place values .
• Always convert the decimal numbers to like decimals , wherever needed.
• Add zeros in the places wherever the length of the decimal numbers is not the same.
• Now, add the numbers and place the decimal point aligned with the given decimal points.

Adding Decimals with Different Decimal Places

Sometimes, the given numbers are different in their length, that is, they do not have an equal number of decimal digits after the decimal point. In such cases, we convert the given decimal numbers to like decimals by adding the required number of zeros to the right of the decimal. This is done to make the process of addition easier. Like decimals have an equal number of digits after the decimal, for example, 0.14 and 2.35 are like decimals, whereas, unlike decimals have different number of digits after the decimal, for example, 6.32 and 6.324 are unlike decimals. So, after the given decimals are changed to like decimals, they are added and the sum is obtained.

Adding Like Decimals

Example: Add: 2.53 + 1.14

If we observe the given decimals, we see that they are like decimals , so, we will place them in order and do the regular addition.

2.53 +1.14 3.67

Therefore, after adding the decimals, we get the sum as 3.67

Adding Unlike Decimals

Example: Add: 6.3 + 2.54

Solution: We can see that the given decimals are unlike, so we will convert them to like decimals by adding the required number of zeros. We will count the number of digits after the decimal point in both the numbers and identify the higher one in them. In this case, 6.3 has one digit after the decimal, and 2.54 has two digits after the decimal. So, will make it 6.30 so that it becomes of the same length as 2.54. Now, we will add the decimals numbers.

Therefore, the sum of the given decimals is 8.84

Adding Decimals with Whole Numbers

Adding decimals with whole numbers is simple to understand. We place a decimal point after the whole number and add the required number of zeros so as to make both the addends of the same length. This is done in such a way that it aligns with the number of digits in the other number. In other words, we convert them to like decimals and then add them.

Example: Add 4 to 6.54

Step 1: We can see that 4 is a whole number and 6.54 is a decimal number. So, let us make both the numbers of equal length.

Step 2: Since there are two digits after the decimal in 6.54, we will place a decimal after 4 and add two zeros after it so that it becomes a decimal number too.

Step 3: Now, we will add the numbers and the sum of the given numbers will be 10.54

Adding Decimals by Regrouping

Adding decimals by regrouping is similar to the regrouping that is done in the addition of whole numbers. Regrouping is also termed as carrying over. In addition, if the sum of the addends is greater than 9 in any of the columns, we regroup it by carrying over the extra digit to the preceding column. Let us understand how to add decimals by regrouping with the following example.

Example: Add 14.62 + 12.63

Let us see how to add the given decimals by regrouping.

• Step 1: Align the given numbers according to their corresponding place value columns and change them to like decimals, if needed. Ensure that the decimal points are aligned with each other.
• Step 2: Start adding digits in each column individually, starting from the right and move to the left in the same way as we do for whole numbers. Add the numbers given in the hundredths column (h). 2 + 3 = 5 and write 5 below the column.
• Step 3: Move to the tenths column (t) and add 6 + 6 = 12. Now, we cannot place '12' in this column since we can write only one digit below each column, so we regroup the number 12. For this, we write 2 in this column and carry 1 to the preceding column, that is, the ones column (O). This 1 (carry-over) is added along with the numbers in the ones column. Remember to place the decimal point below the decimal point.
• Step 4: Now, let us add the numbers under the ones column. Here, after the carry-over is placed in this column, it is added along with the other addends. This will be, 4 + 2 + 1 (carry-over) = 7.
• Step 5: Finally, add the numbers given in the tens column (T), that is, 1 + 1 = 2.

Thus, the sum of the numbers 14.62 + 12.63 is 27.25

Tips and Tricks for Adding Decimals

• We always start adding decimals from the right-hand side, like in the case of the addition of two whole numbers.
• The decimal points are always aligned below the decimal point.
• The addition of two decimal numbers can be treated as the addition of two whole numbers initially and the decimal places can be placed in the end to avoid confusion.

Adding Decimals Examples

Example 1: Add the decimal numbers: 20.62 and 13.01

Solution: For adding decimals, we first need to align them according to their place values and ensure that the decimal point is aligned too.

20.62 +13.01 33.63

Therefore, the sum of the given decimal numbers is 33.63

Example 2: Add the decimal numbers: 4.68 and 3.01

Solution: While adding decimals, we place the numbers in order as per their place values keeping the decimal point intact.

4.68 + 3.01 7.69

Therefore, the sum of the given decimal numbers is 7.69

Example 3: State true or false:

a.) When the given numbers are different in their length, we convert them to unlike decimals.

b.) Like decimals have an equal number of digits after the decimal, for example, 0.34 and 2.63 are like decimals.

a.) False, when the given numbers are different in their length, we convert them to like decimals.

FAQs on Adding Decimals

What is addition of decimals.

Addition of decimals means adding decimal numbers following a few rules. Adding decimals is similar to the usual addition of whole numbers. When we add decimal numbers, we align them according to their place values keeping in mind the decimal point that should be placed correctly.

What is the Rule for Adding Decimals?

For adding decimals, we need to remember the following rules that would make the process of addition easier.

• Align the decimal numbers in such a manner that they are placed in the correct column according to their place values.
• Remember to convert the decimal numbers to like decimals , wherever needed.
• Add zeros in the places wherever the length of the decimal numbers is not equal.
• Finally, add the numbers and place the decimal point aligned with the given decimal points.

How to Add Decimals By Regrouping?

While adding decimals, the regrouping of numbers is done in the same way as in the addition of whole numbers. The important thing to be kept in mind is that the decimal point and all the numbers should be aligned correctly according to the place values. Regrouping in decimals is done if the sum of the addends is greater than 9 in any of the columns. Then, the extra digit is carried over to the preceding column. For example, if we need to add 3.6 and 2.9, we will start adding the tenths column, which is 6 + 9 = 15. But we cannot place 15 here since only one digit is placed under one column. So, we will write 5 in this column and carry over 1 to the ones column. This is how we regrouped 15. Then, moving on to the ones column, we will add the given numbers along with this carry-over. This will be, 3 + 2 + 1 (carry-over) = 6.5. Therefore, the sum will be 6.5

How to Add Decimals with Whole Numbers?

We add decimals with whole numbers in a very simple way. We place a decimal point after the whole number and write the required number of zeros after the decimal so as to make both the numbers of the same length. In other words, we change them to like decimals and then add them. For example, if we need to add 5 + 3.23, we will change 5 to 5.00 and then add it to 3.23. So, 5.00 + 3.23 = 8.23

How to Add Decimals and Fractions?

In order to add decimals and fractions, we can use the following steps. Let us understand this by adding 14.32 + 1/4. Here 14.32 is a decimal and 1/4 is a fraction .

• Step 1: Convert the fraction into its decimal form. So, the fraction 1/4 is written as 0.25 in the decimal form.
• Step 2: Write the numbers such that the decimals are aligned according to their place values.Here, 14.32 + 0.25
• Step 3: Place zero in the places if the length of decimal numbers is not the same and add the numbers as we add whole numbers, starting from the right and move to the left. Here they are of the same length, therefore, we can move on.
• Step 4: So, the sum of the given numbers is 14.32 + 0.25 = 14.57

How to Add Decimals with Different Decimal Places?

If the given set of decimal numbers have different number of digits after the decimal point, they are called unlike decimal fractions . In this case, we count the number of digits after the decimal point in both the numbers and identify the higher one in them. After this step, we add the required number of zeros to the smaller decimal number so that it becomes of the same length as the other number. After this, we add the decimals numbers. For example, if we need to add 23.3 and 12.456, we will make it 23.300 + 12.456 and then add them. So, the sum will be 23.300 + 12.456 = 35.756

What are the Steps for Adding Decimals?

There are some basic steps that are used for adding decimals.

• Step 1: First of all, align the decimal numbers according to their place values.
• Step 2: Then, convert the decimal numbers to like decimals , if needed.
• Step 3: Finally, add the numbers and place the decimal point aligned with the given decimal points.

How is Adding Decimals Similar to Subtracting Decimals?

Adding decimals is similar to subtracting decimals because some common rules are followed in both the operations.

• In the addition and subtraction of decimals, we need to place the decimal numbers one below the other in such a way that they are aligned according to their place values along with the decimal point.
• We also need to change the given decimal fractions to like decimals so that the process of addition or subtraction becomes easier.
• After converting the given decimals to like decimals , by adding the required number of zeros, we add or subtract the given numbers in the regular way in which we add or subtract whole numbers.

Adding and Subtracting Decimals – Definition With Examples

Decimal number, decimals in real life, steps to add decimals, solved examples, practice problems, frequently asked questions.

• A decimal number is a fraction whose denominator is a power of 10. For example, the fraction 4⁄10 can be written in decimal form as 0.4.
• The dot in decimal numbers is called the decimal point .
• The number to the right of the decimal point denotes the numerator of the fraction, that is, the fractional part.
• The number to the left of the decimal point denotes the whole number part of the fraction .
• For example, 4 3⁄10  is expressed as 4.3, where 4 is the whole number part and 0.3 is the fractional part. The decimal point separates the whole number part from the fractional part. 

Recommended Games

In day-to-day life, we need to find the sum or total or find the differences in values. The values of length, weight, money, etc., are not always written in the whole numbers, the values are in decimals also. We use decimal addition and subtraction in everyday life when dealing with:

• Measurements (length, mass, capacity)
• Temperature

For that, we need to understand how to add and subtract decimals. Decimals can be added or subtracted the same way we add or subtract whole numbers.

Step 1: Convert decimals to like decimals.

Decimals that have the same number of digits after the decimal point are called like decimals. 3.42, 2.89, 5.14 are all like decimals because they all have 2 digits after the decimal point.

To make decimals like, we can add zeros on the right of extreme right digits in the decimal part of a number as that does not alter the value. 

For example, 3.4 is the same as 3.40, which is also the same as 3.400.

Step 2: Write the decimals one below the other as per the places of the digits.

Step 3: Add starting from the rightmost digit and moving toward the leftmost digit.

Step 4: Place the decimal point under the decimal point in the answer. 

Example of Addition of Decimals

Let us use the above steps to solve the following.

Add 23.45, 13.101, and 345.5 

Step 1.  Convert to like decimals. 

The maximum digits after the decimal place are 3, so we add zeros in other numbers to get 3 decimal places in all of them.

    13.101

    23.45 = 23.450

    345.5 = 345.500

Step 2.  Line up the decimals.

Step 3.  Add:

Step 4.  Place the decimal point in the answer.

Example: Sienna purchased three laces of length 45 m 50 cm, 23 m 83 cm and 16 m 5 cm. She joined them together to get lace of the greatest length. Find the length of the single string obtained.

To find the length of a single string, we need to add the lengths of all three laces.

• Write the length of laces as decimal numbers.

45 m 50 cm = 45.50 m

23 m 83 cm = 23.83 m

16 m 5 cm = 16.05 m

• Convert to like decimals.

The highest decimal place is 2. All the numbers have 2 decimal places, so they are already like decimals.

• Line up the decimals.

• Place the decimal in the answer.

Once you know how to add decimals, subtracting them is quite similar. You must be wondering how is adding and subtracting decimals similar? Let’s look at the steps.

Steps to Subtract Decimals

Step 1: Convert unlike decimals into like decimals.

Step 2 : Write the digits in their respective columns according to the place.

Step 3 : Put the decimal point one below the other so that all the decimal points are in the same vertical line. 

Step 4 : Start subtracting from the rightmost digit and move toward the leftmost digit.

Step 5 : Place the decimal point under the decimal point in the answer. 

Examples of Subtraction of Decimals

Example 1. Subtract 12.856 from 54.2

1.   Convert to like decimals : The highest decimal place is 3, so we add zeros in the other numbers and get 3 decimal places in that too.

12.856 and 54.2 = 54.200

2 .   Line up the decimals .

3. Subtract the decimals.

4. Place the decimal point in the answer.

Example 2. Kylie had 25 m 10 cm of ribbon. She uses 8 m and 13 cm to decorate a skirt. How much ribbon is Kylie left with?

Length of ribbon Kylie had = 25 m 10 cm = 25.10         

Length of ribbon used by Kylie = 8 m 13 cm = 8.13

The remaining length of ribbon = 25.10 – 8.13

= 16 m 97 cm

Addition and Subtraction of Decimals with Whole numbers

To add or subtract a decimal with a whole number, change the whole number into a decimal number. A whole number can be changed to a decimal number by placing a decimal point after the whole number and writing the required number of zeros after the decimal point.

For example, the whole number 2 can be written as 2.0 or 2.00 or 2.000 and so on.

Similarly, 6 = 6.0 = 6.00 = 6.000 = 6.000 and so on.

Now follow the steps of addition and subtraction of decimals. 

Example: Add 4 + 5.93 + 7

• Convert whole numbers to decimals and make all decimals like decimals.

The highest decimal place is 2, so let’s rewrite all numbers as decimal numbers with 2 decimal places to make them like decimals.

• Add the decimals.

• Place the decimal point in the answer.

Example: Subtract 19.523 from 21.

• Convert a whole number to a decimal number with similar decimal places.

19.523 has 3 decimal places, so let’s rewrite 21 = 21.000

• Subtract the decimals.

In 5th grade adding and subtracting decimals is done. 5th graders must practice adding and subtracting decimals word problems too along with simple decimal problems.

Example 1: Add 0.56, 12.356, and 152.3

The highest decimal place is 3, so let’s change all decimals to like decimals.

0.56 = 0.560

152.3 = 152.300

Line up the decimals and add and place the decimal in place.

Example 2: Solve 920.45 – 222.339

The highest decimal place is 3, so let’s change 920.45 to 92.450. 

Now let’s line up the decimals and subtract them.

Now let’s practice adding and subtracting decimals word problems.

Example 3: Siran bought two articles worth $120.45 and $450.85. She paid $700 to the shopkeeper. How much money will she get back from the shopkeeper?

 Total cost of article = $120.45 + $450.85 = $571.30

Money returned by shopkeeper = $700 – $571.30 = $128.70

So, Siran will get back $128.70 from the shopkeeper.
