The first step to changing 18 15/4 into a decimal is to change it to an improper fraction. To do that, we need to multiply 18 by 4 and add its product to 15 in the numerator to get: 87/4. Now we will attempt to convert 87/4 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 87 by the denominator 4:
87 (numerator) ÷ 4 (denominator) = 21.75
As a result, you get 21.75 as your answer when you convert 18 15/4 (or 87/4) to a decimal.
