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 32:
90 (numerator) ÷ 32 (denominator) = 2.81
As a result, you get 2.81 as your answer when you convert 1 58/32 (or 90/32) to a decimal.
