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 5:
139 (numerator) ÷ 5 (denominator) = 27.8
As a result, you get 27.8 as your answer when you convert 10 89/5 (or 139/5) to a decimal.
