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 80:
90 (numerator) ÷ 80 (denominator) = 1.13
As a result, you get 1.13 as your answer when you convert 90/80 to a decimal.
