Question

A recipe for fruit punch calls for cranberry juice and sparkling water. The ratio of cups of cranberry juice to cups of sparkling water is 6:24. According to the recipe, how many cups of cranberry juice are needed for every one and a half cup of sparkling water? Write your answer in simplest form.

Answer 1

So we'll start by looking at the ratio (fraction).

6 / 24, or more fittingly, sparkling water / cranberry juice.

We can simplify the fraction to find an easy point of reference.

6 / 24 = 1 / 4

So if we're being asked for every one and a half cups, we'll get this fraction: 1.5 / 6.

It's about 6 cups of cranberry juice for every one and a half cups of sparkling water.  Or was it the other way around?  I only know the ratio, you figure out the rest.

Hope this helps!
