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

irga5000 [103]

Answer:

28 Students

Step-by-step explanation:

Let's break down all of our variables.

$\dfrac{1}{4}$ likes strawberry

$\dfrac{1}{2}$ likes chocolate

7 likes vanilla

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

$\dfrac{1}{4}+\dfrac{1}{2}=\dfrac{3}{4}$

This then tells us that the 7 kids that like vanilla are the remaining $\dfrac{1}{4}$ of the class.

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

$\dfrac{1}{4}=\dfrac{7}{x}$

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.
