Question

a punch recipe calls for 1 liter of lemon soda for every 3 liters of fruit juice. If a woman uses 10 liters of fruit juice how many liters of lemon soda does she need

Answer 1

Answer: 3
`(1)/(3)` liters

Explanation:

We will set up a proportion to help us solve.

`\displaystyle \frac{10 \text{ liters of fruit juice}}{x\text{ liters of lemon soda}} =\frac{3 \text{ liters of fruit juice}}{1\text{ liters of lemon soda}}`

Now we will cross multiply.

10 = 3x

Lastly, we will divide both sides by 3.

3
`(1)/(3)` = x

She will need 3
`(1)/(3)` liters of lemon soda.
