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 135 by the denominator 9:
135 (numerator) ÷ 9 (denominator) = 15
As a result, you get 15 as your answer when you convert 13 18/9 (or 135/9) to a decimal.
