Answer 1

Given:

Elise is making punch for the party that requires 2 parts of fruit juice for every 5 parts of ginger ale.

To make the punch, she uses 18 ounces of fruit juice and 3 containers of ginger ale.

To find:

The number of ounces in each container of ginger ale.

Solution:

Let n be the number of ounces in each container of ginger ale.

According to the question, the ratio of fruit juice and ginger ale is 2:5. it means,

$\dfrac{\text{Fruit juice}}{\text{Ginger}}=\dfrac{2}{5}$

$\dfrac{18}{\text{Ginger}}=\dfrac{2}{5}$

$5\times 18=2\times \text{Ginger}$

$90=2\times \text{Ginger}$

Divide both sides by 2.

$45=\text{Ginger}$

So, ginger required for punch is 45 ounces.

Number of containers = 3

Number of ounces in each container of ginger ale = n

Number of ounces in 3 containers of ginger ale = 3n

Now,

$3n=45$

Divide both sides by 3.

$n=15$

Therefore, 15 ounces are in each container of ginger ale.
