The first step to changing 1 40/20 into a decimal is to change it to an improper fraction. To do that, we need to multiply 1 by 20 and add its product to 40 in the numerator to get: 60/20. Now we will attempt to convert 60/20 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 60 by the denominator 20:
60 (numerator) ÷ 20 (denominator) = 3
As a result, you get 3 as your answer when you convert 1 40/20 (or 60/20) to a decimal.
