Let’s learn more about decimal numbers. 

What are decimal numbers?

The decimal numbers are a mix of fractions and whole numbers. The whole number part is separated from the fraction by the decimal point.

An example of a decimal number is 98.9. The 98 on the left side is the whole number. Then comes the decimal point and at the end is the 9 for the fraction which actually means 9/10.

You can convert any fraction to decimal using the fraction to decimals calculator

How to add or subtract decimal numbers?

The technique of adding or subtracting decimal numbers is easy. Use the calculator, just kidding ????. Simply add the whole numbers to whole numbers and fraction part to the other fraction part. 


Add the following numbers: 561.1 and 234.9.


Step 1: Write the numbers above each other.

   5 6 1 . 1

+ 2 3 4 . 9


Step 2: Add the numbers.

   5 6 1 . 1

+ 2 3 4 . 9


   7 9 6 . 0

An example of subtraction using the same numbers.

After writing the numbers, start subtracting. Take one carry from the left to the right. The 1 on the right will become 11. 

  5 6 1 . 1

- 2 3 4 . 9


   3 2 6 . 2

How to divide or multiply the decimal numbers?

The multiplication or division techniques of decimals are a little different from the whole numbers. In multiplying, the only difference comes in placing the decimal point.

For clarity, see the example ahead.


Multiply 67.3 by 7.1.


Step 1: Multiply the numbers.

6 7 . 3

x 7 . 1


     6 7 3

4 7 1 1 x

4 7 7 8 3

Step 2: Count the digits after decimal points in both numbers collectively and place the decimal point after counting the same amount of digits from the right. 

There are 2 digits so the point will be placed after 2 digits from the right like 477.83.

In dividing the decimal numbers, you have to see if the divisor is a whole number or not. It must be a whole number to carry out the division.


Divide 5.76 by 0.3


Step 1: Convert decimal to the whole number.

If we want to change the divisor, the same changes will be applied to the dividend. 

Multiply both values with 10. 

5.76 x 10 = 57.6 , 0.3 x 10 = 3

Step 2: Now divide.

Hence; 5.76/0.3 = 19.2

These were the basic four operations. Hope this helps.
