Question 280063
Using the information given, the ratio of vodka to the other ingredients is (1/6).
That is, there is one part vodka in 6 parts of the punch.

So how much vodka in 120 ounces?

{{{Vodka = (1/6) * total}}}
{{{Vodka = (1/6) * 120}}}
{{{Vodka = 20}}}

I hope this isn't a recipe included in the school student recipe collection.
