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 300:
90 (numerator) ÷ 300 (denominator) = 0.3
As a result, you get 0.3 as your answer when you convert 90/300 to a decimal.
