A fraction is written in terms of two parts: the number on top is called the numerator and the number on the bottom is called the denominator. We can use the division method to solve this question. To get a decimal, simply divide the numerator 100 by the denominator 25:
100 (numerator) ÷ 25 (denominator) = 4
As a result, you get 4 as your answer when you convert 3 25/25 (or 100/25) to a decimal.
