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 133 by the denominator 23:
133 (numerator) ÷ 23 (denominator) = 5.78
As a result, you get 5.78 as your answer when you convert 3 64/23 (or 133/23) to a decimal.
