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 123 by the denominator 13:
123 (numerator) ÷ 13 (denominator) = 9.46
As a result, you get 9.46 as your answer when you convert 3 84/13 (or 123/13) to a decimal.
