Mathematics is based on fractions. Fractions can also be used for all the fundamental operations performed on integers.

The following steps can be used to convert a decimal number into a fraction.

Step 1: In the numerator, place the given number, and in the denominator, place 1 in the decimal place followed by the number of zeroes required accordingly.

In this case, 1.5 has one number after the decimal point. so, we place 10 in the denominator and remove the decimal point. This will make it 15/10

Step 2: Then, this fraction can be simplified. 15/10 = (15 ÷ 5)/(10 ÷ 5) = 3/2
