One method to convert 31/15 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 31 by the denominator 15:
31 (numerator) ÷ 15 (denominator) = 2.07
And there you go! We got 2.07 as the answer when you convert 2 1/15 (or 31/15) to a decimal.
