The first step to changing 4 21/20 into a decimal is to change it to an improper fraction. To do that, we need to multiply 4 by 20 and add its product to 21 in the numerator to get: 101/20. Now we will attempt to convert 101/20 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 101 by the denominator 20:
101 (numerator) ÷ 20 (denominator) = 5.05
As a result, you get 5.05 as your answer when you convert 4 21/20 (or 101/20) to a decimal.
