The first step to changing 40 19/3 into a decimal is to change it to an improper fraction. To do that, we need to multiply 40 by 3 and add its product to 19 in the numerator to get: 139/3. Now we will attempt to convert 139/3 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 139 by the denominator 3:
139 (numerator) ÷ 3 (denominator) = 46.33
As a result, you get 46.33 as your answer when you convert 40 19/3 (or 139/3) to a decimal.
