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 91 by the denominator 9:
91 (numerator) ÷ 9 (denominator) = 10.11
As a result, you get 10.11 as your answer when you convert 3 64/9 (or 91/9) to a decimal.
