Question

There are 32 students in a class. Of the class, 3/8 of the students bring their own lunches. How many students bring their lunches?

Answer 1

The number of students that bring their lunches is 12

Explanation:

Let

x -----> the number of students that bring their lunches

y -----> the total number of students in a class

we know that

The number of students that bring their lunches divided by the total number of students in a class must be equal to 3/8

`(x)/(y)=(3)/(8)`

`x=(3)/(8)y` -----> equation A

`y=32` -----> equation B

substitute the value of y in equation A and solve for x

`x=(3)/(8)(32)`

`x=12`

therefore

The number of students that bring their lunches is 12
