The first step to changing 2 42/7 into a decimal is to change it to an improper fraction. To do that, we need to multiply 2 by 7 and add its product to 42 in the numerator to get: 56/7. Now we will attempt to convert 56/7 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 56 by the denominator 7:
