One method to convert 100/45 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 100 by the denominator 45:
100 (numerator) ÷ 45 (denominator) = 2.22
And there you go! We got 2.22 as the answer when you convert 2 10/45 (or 100/45) to a decimal.
