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 17:
139 (numerator) ÷ 17 (denominator) = 8.18
As a result, you get 8.18 as your answer when you convert 7 20/17 (or 139/17) to a decimal.
