Question

The kids in Mrs. B's class did a survey about their favorite flavors of ice cream. One-fourth of the class likes strawberry the best. One-half of the class likes chocolate the best. The rest of the class, 7 kids, said vanilla is their favorite ice cream flavor. How many kids are in Mrs. B's class?

Answer 1

28 Students

Explanation:

Let's break down all of our variables.

`(1)/(4)` likes strawberry

`(1)/(2)` likes chocolate

7 likes vanilla

First we need to combine the number of students that like strawberry and chocolate.

`(1)/(4)+(1)/(2)=(3)/(4)`

This then tells us that the 7 kids that like vanilla are the remaining
`(1)/(4)` of the class.

Let's use ratio to find out how many students there are in total.

`(1)/(4)=(7)/(x)`

Let x = number of student in Mrs. B's class.

We need to multiply 4 to 7 and x to 1.

So that leave us with:

x = 28

There are 28 students total in Mrs. B's class.
