Jake makes a drink that is 2 parts Coke, 1 part Sprite and 3 parts Mountain Dew. If the drink contains 6 ounces of Coke, how many ounces is the drink? Think carefully first, then make a decision:
The drink is 2 + 1 + 3 = 6 parts. The drink is 2 / 6 = 1 / 3 coke. So the drink is 6 / (1 / 3) = 18 ounces. So, the answer is 18.
