One method to convert 90/300 to a decimal is by using the division method. Before we move ahead to the method, here is a quick recap on fractions: A fraction is a number representation that is broken down into two parts - the number on top is called the numerator, and the number on the bottom is called the denominator. To get a decimal using the division method, simply divide the numerator 90 by the denominator 300:
90 (numerator) ÷ 300 (denominator) = 0.3
And there you go! We got 0.3 as the answer when you convert 90/300 to a decimal.
