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 143 by the denominator 13:
143 (numerator) ÷ 13 (denominator) = 11
As a result, you get 11 as your answer when you convert 8 39/13 (or 143/13) to a decimal.
