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.

Andries get grandfather get offered to give him a gift of 50% of the amount of money he saved in one year. And Ray saved $120. H

sertanlavr [38]

Answer:

$60

Step-by-step explanation:

The savings of Andries is $120 and his grandfather offered that he would give 50% of the amount he saved.

50% is actually just half of a given amount. So the short way to do this is just half the saving of Andries.

$\dfrac{\$120}{2} = \$60$

You can also think of it this way:

$50\%=\dfrac{50}{100}$

So we multiply that to the amount saved to solve for what is 50% of 120.

$\$120\times\dfrac{50}{100} = \dfrac{\$6000}{100}=\$60.00$
