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 2:
133 (numerator) ÷ 2 (denominator) = 66.5
As a result, you get 66.5 as your answer when you convert 9 115/2 (or 133/2) to a decimal.
