The first step to changing 5 21/5 into a decimal is to change it to an improper fraction. To do that, we need to multiply 5 by 5 and add its product to 21 in the numerator to get: 46/5. Now we will attempt to convert 46/5 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 46 by the denominator 5:
46 (numerator) ÷ 5 (denominator) = 9.2
As a result, you get 9.2 as your answer when you convert 5 21/5 (or 46/5) to a decimal.
