One method to convert 20/7 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 20 by the denominator 7:
20 (numerator) ÷ 7 (denominator) = 2.86
And there you go! We got 2.86 as the answer when you convert 2 6/7 (or 20/7) to a decimal.
