Final answer:
Adrian uses a certain ratio of cups of Cheetos to cups of Doritos in his snack mix. To find how many cups of Cheetos he uses for 1 cup of Doritos, set up and solve a proportion.
Step-by-step explanation:
To find out how many cups of Cheetos Adrian uses for 1 cup of Doritos, we need to set up a ratio between the amounts of Cheetos and Doritos he uses. We know that he uses 2 3/4 cups of Cheetos for every 1/2 cup of Doritos.
First, convert the mixed number to an improper fraction. 2 3/4 can be rewritten as 11/4.
Then, set up a proportion: (Cheetos cups / Doritos cups) = (11/4 / 1/2).
Finally, cross multiply and solve for Cheetos cups to find the answer.
