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 126:
90 (numerator) ÷ 126 (denominator) = 0.71
As a result, you get 0.71 as your answer when you convert 90/126 to a decimal.
