The first step to changing 7 78/6 into a decimal is to change it to an improper fraction. To do that, we need to multiply 7 by 6 and add its product to 78 in the numerator to get: 120/6. Now we will attempt to convert 120/6 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 120 by the denominator 6:
120 (numerator) ÷ 6 (denominator) = 20
As a result, you get 20 as your answer when you convert 7 78/6 (or 120/6) to a decimal.
