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 84 by the denominator 8:
84 (numerator) ÷ 8 (denominator) = 10.5
As a result, you get 10.5 as your answer when you convert 10 4/8 (or 84/8) to a decimal.
