The first step to changing 3 77/18 into a decimal is to change it to an improper fraction. To do that, we need to multiply 3 by 18 and add its product to 77 in the numerator to get: 131/18. Now we will attempt to convert 131/18 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 131 by the denominator 18:
131 (numerator) ÷ 18 (denominator) = 7.28
As a result, you get 7.28 as your answer when you convert 3 77/18 (or 131/18) to a decimal.
