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 57 by the denominator 64:
57 (numerator) ÷ 64 (denominator) = 0.89
As a result, you get 0.89 as your answer when you convert 57/64 to a decimal.
