One method to convert 128/3 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 128 by the denominator 3:
128 (numerator) ÷ 3 (denominator) = 42.67
And there you go! We got 42.67 as the answer when you convert 5 113/3 (or 128/3) to a decimal.
