Answer:
8 cups
Explanation:
Given a recipe for trail mix that calls for 1 cup of nuts for each 2 cups of granola, you want to know the number of cups of granola required for 12 cups of trail mix.
Fraction
The fraction of the total volume of trail mix that is granola is ...
granola / (trail mix) = granola / (nuts + granola)
(2 cups)/(1 cup +2 cups) = 2/3
Applied to the quantity 12 cups of trail mix, we find the volume of granola to be ...
granola = (2/3)×(12 cups) = 8 cups
You need 8 cups of granola for 12 cups of trail mix.
