The first step to changing 7 12/8 into a decimal is to change it to an improper fraction. To do that, we need to multiply 7 by 8 and add its product to 12 in the numerator to get: 68/8. Now we will attempt to convert 68/8 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 68 by the denominator 8:
68 (numerator) ÷ 8 (denominator) = 8.5
As a result, you get 8.5 as your answer when you convert 7 12/8 (or 68/8) to a decimal.
