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 20 by the denominator 129:
20 (numerator) ÷ 129 (denominator) = 0.16
As a result, you get 0.16 as your answer when you convert 20/129 to a decimal.
