The first step to changing 7 30/8 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 30 in the numerator to get: 86/8. Now we will attempt to convert 86/8 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 86 by the denominator 8:
