In order to convert decimal into fraction; follow the following steps:

Step 1: Numerator of fraction is equal to decimal (without the decimal point)

Step 2: Find number of Decimal Place in the given decimal

Step 3: Denominator of fraction is equal to 1 followed by as many number of zero as there are decimal place.

Example: Convert decimal 4.2 into fraction.

Solution: Follow the steps as explained above:

Step 1: Numerator of fraction is equal to decimal (without the decimal point) and we get: Numerator = 42

Step 2 : Find number of Decimal Place in the given decimal and we get:
Decimals Places = one only

Step 3: Denominator of fraction is equal to 1 followed by as many number of zero as there are decimal places.
As calculated in step 2, there is only one decimal place, so we will write one zero next to digit 1 and we get:
Denominator = 10

Now, we know that:

Fraction =

Numerator Denominator

Put the values of numerator and denominator from step 1 & Step 3 and we get:
