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 39:
20 (numerator) ÷ 39 (denominator) = 0.51
As a result, you get 0.51 as your answer when you convert 20/39 to a decimal.
