Hi!
So basically, you can set this up in a proportion.
For every gallon of punch, 2 cups of cranberry juice is needed. What you need to find is the amount of cranberry juice is needed for one gallon. So then you would have to set up your proportion like this:
[tex] \frac{2}{3} = \frac{x}{1} [/tex]
then you would have to cross multiply, and you should have something like this:
3x = 2
then using division you should have this:
x = [tex] \frac{2}{3} [/tex]
so you would need 2/3 cups of cranberry juice for one gallon of punch. :)
hopefully this makes sense, lol.
