The first step to changing 3 42/4 into a decimal is to change it to an improper fraction. To do that, we need to multiply 3 by 4 and add its product to 42 in the numerator to get: 54/4. Now we will attempt to convert 54/4 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 54 by the denominator 4:
54 (numerator) ÷ 4 (denominator) = 13.5
As a result, you get 13.5 as your answer when you convert 3 42/4 (or 54/4) to a decimal.
