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 144 by the denominator 15:
144 (numerator) ÷ 15 (denominator) = 9.6
As a result, you get 9.6 as your answer when you convert 9 9/15 (or 144/15) to a decimal.
