The first step to changing 1 21/39 into a decimal is to change it to an improper fraction. To do that, we need to multiply 1 by 39 and add its product to 21 in the numerator to get: 60/39. Now we will attempt to convert 60/39 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 39:
60 (numerator) ÷ 39 (denominator) = 1.54
