The first step to changing 42 27/2 into a decimal is to change it to an improper fraction. To do that, we need to multiply 42 by 2 and add its product to 27 in the numerator to get: 111/2. Now we will attempt to convert 111/2 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 111 by the denominator 2:
111 (numerator) ÷ 2 (denominator) = 55.5
As a result, you get 55.5 as your answer when you convert 42 27/2 (or 111/2) to a decimal.
