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 89 by the denominator 50:
89 (numerator) ÷ 50 (denominator) = 1.78
As a result, you get 1.78 as your answer when you convert 1 39/50 (or 89/50) to a decimal.
