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 90 by the denominator 33:
90 (numerator) ÷ 33 (denominator) = 2.73
As a result, you get 2.73 as your answer when you convert 1 57/33 (or 90/33) to a decimal.
