One method to convert 140/20 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 140 by the denominator 20:
140 (numerator) ÷ 20 (denominator) = 7
And there you go! We got 7 as the answer when you convert 5 40/20 (or 140/20) to a decimal.
