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 109 by the denominator 11:
109 (numerator) ÷ 11 (denominator) = 9.91
As a result, you get 9.91 as your answer when you convert 8 21/11 (or 109/11) to a decimal.
