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 16:
139 (numerator) ÷ 16 (denominator) = 8.69
As a result, you get 8.69 as your answer when you convert 1 123/16 (or 139/16) to a decimal.
