One method to convert 121/27 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 121 by the denominator 27:
121 (numerator) ÷ 27 (denominator) = 4.48
And there you go! We got 4.48 as the answer when you convert 3 40/27 (or 121/27) to a decimal.
