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 129 by the denominator 31:
129 (numerator) ÷ 31 (denominator) = 4.16
As a result, you get 4.16 as your answer when you convert 129/31 to a decimal.
