Math Tutor Solution: 3 21/40 as a decimal is 3.53
Methods
First step from a math tutor – Making the fraction improper:
The first step to changing 3 21/40 into a decimal is to change it to an improper fraction. To do that, we need to multiply 3 by 40 and add its product to 21 in the numerator to get: 141/40. Now we will attempt to convert 141/40 to a decimal using the following method.
A Math Tutor's explanation using the division 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 141 by the denominator 40:
141 (numerator) ÷ 40 (denominator) = 3.53
As a result, you get 3.53 as your answer when you convert 3 21/40 (or 141/40) to a decimal.
