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 137 by the denominator 39:
137 (numerator) ÷ 39 (denominator) = 3.51
As a result, you get 3.51 as your answer when you convert 2 59/39 (or 137/39) to a decimal.
