The first step to changing 4 90/15 into a decimal is to change it to an improper fraction. To do that, we need to multiply 4 by 15 and add its product to 90 in the numerator to get: 150/15. Now we will attempt to convert 150/15 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 150 by the denominator 15:
150 (numerator) ÷ 15 (denominator) = 10
As a result, you get 10 as your answer when you convert 4 90/15 (or 150/15) to a decimal.
