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 99 by the denominator 129:
99 (numerator) ÷ 129 (denominator) = 0.77
As a result, you get 0.77 as your answer when you convert 99/129 to a decimal.
