One method to convert 18/3 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 18 by the denominator 3:
18 (numerator) ÷ 3 (denominator) = 6
And there you go! We got 6 as the answer when you convert 5 3/3 (or 18/3) to a decimal.
