One method to convert 81/31 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 81 by the denominator 31:
81 (numerator) ÷ 31 (denominator) = 2.61
And there you go! We got 2.61 as the answer when you convert 1 50/31 (or 81/31) to a decimal.
