One method to convert 128/5 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 5:
128 (numerator) ÷ 5 (denominator) = 25.6
And there you go! We got 25.6 as the answer when you convert 17 43/5 (or 128/5) to a decimal.
