One method to convert 131/2 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 131 by the denominator 2:
131 (numerator) ÷ 2 (denominator) = 65.5
And there you go! We got 65.5 as the answer when you convert 45 41/2 (or 131/2) to a decimal.
