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 133 by the denominator 15:
133 (numerator) ÷ 15 (denominator) = 8.87
As a result, you get 8.87 as your answer when you convert 3 88/15 (or 133/15) to a decimal.
