In this post we will learn how to subtract decimal numbers.

The concept is easy and very similar to subtraction of whole numbers.

**How to subtract decimals**

In order to subtract the decimals, do the following steps:

**(a) Decimal Place Values**

Make sure that both the number have same place values after decimals.

For number with less decimal place value, insert 0 at the end of the decimal number

**(b) Vertical Arrangement**

Vertically arrange both the numbers such that digits with same place values are in same line.

**(c) Subtract the numbers**

Start subtracting numbers from left to right.

The process is same as you subtract the whole numbers.

These are the three easy steps for subtraction of decimals.

Now enough with the theory, let’s study the concept with some examples.

**Example 01**

Subtract 2.3 with 1.1

**Solution**

Let’s follow the above three steps of decimal subtraction**(a) Place Value of numbers**

Both the given number have same decimal place values

2.3 ⟹ One place value after decimal

1.1 ⟹ One place value after decimal

Hence, no changes needed in this step

**(b) Vertical Arrangement**

Arrange numbers such that number with same place values are in same line

**(c) Subtract numbers from right to left **

The above subtraction completes using below steps:

⟹ Subtracting Tenth Place Value ( 3 – 1 = 2)

⟹ Subtracting Ones Place Value ( 2 – 1 = 1 )

Hence, **1.2 is the solution**

**Example 02**

Subtract 17.6 – 5.23

Solution

Follow the three steps as mentioned above:**(a) Decimal Place Values**

17.6 ⟹ one decimal value

5.23 ⟹ two decimal value

We need all numbers with same decimal place value.

So we add zero at the end of 17.6

**(b) Vertical Arrangement**

Arrange numbers vertically so that digits with same place values are in same line

**(c) Subtract numbers from right to left**

Hence, **12.37 is the solution**

**Example 03**

Subtract 6.003 with 0.33

Solution

Follow the below steps:

**(a) Decimal Place Values**

Here numbers have different number of decimal digits

6.003 ⟹ three decimal digits

0.33 ⟹ two decimal digits

To make decimal digits equal on both numbers, we have to add zero at the end of 0.33

**(b) Arrange numbers vertically**

Both the numbers are arranged in such way that digits with same place values are in same line

**(c) Subtract numbers from right to left**

Hence, **5.673 is the solution**

**Example 04**

Subtracting decimal from Whole number

⟹ 24 – 13.55

Solution

The Subtraction process is same as we discussed above

(a) Decimal Place Value

24 ⟹ No Decimal Place

13.55 ⟹ Two decimal Number

So we insert two zeros after decimal in 24, so that all number have same decimal digits.

(b) Vertical Arrangement

Arrange numbers vertically so digits with same place value are in same line

(c) Start subtraction from right to left

**10.45 is the right answer**

**Example 05**

Subtract 9452.12 with 736.628

Solution**(a) Place values of decimal**

9452.12 ⟹ has two decimal digits

736.628 ⟹ has three decimal digits

Insert 0 at the end of 9452.12 to make both the numbers with same decimal place

**(b) Arrange numbers vertically**

**(c) Subtract number from right to left**

**8715.492 is the solution**
