One method to convert 120/23 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 120 by the denominator 23:
120 (numerator) ÷ 23 (denominator) = 5.22
And there you go! We got 5.22 as the answer when you convert 3 51/23 (or 120/23) to a decimal.
