The first step to changing 18 20/6 into a decimal is to change it to an improper fraction. To do that, we need to multiply 18 by 6 and add its product to 20 in the numerator to get: 128/6. Now we will attempt to convert 128/6 to a decimal using the following method.
A fraction is written in terms of two parts: the number on top is called the numerator and the number on the bottom is called the denominator. We can use the division method to solve this question. To get a decimal, simply divide the numerator 128 by the denominator 6:
128 (numerator) ÷ 6 (denominator) = 21.33
