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 139 by the denominator 2:
139 (numerator) ÷ 2 (denominator) = 69.5
As a result, you get 69.5 as your answer when you convert 35 69/2 (or 139/2) to a decimal.
