1) Get the number at the left side of the decimal
point. This will be your whole number.

Whole number = 2

2) Get the number at the right side of the decimal
point. This will be your denominator.

Numerator = 25

3) Count how many decimal places are there. Put 1 as the denominator and write as many
zeros as the decimal places. There are two decimal places, so the denominator =
100
