Answer 1

This problem is about tape diagrams which are used to help the student to visualize the problem.

In this case, we have three portions of red paint, and 2 portions of yellow paint, this means the ratio of red paint to yellow paint is 3:2.

On the other hand, the ratio of yellow paint to red paint is 2:3 (a), the opposite.

Since we have three cups of red paint and two cups of yellow paint, we can deduct that the mixture has 5 cups in total. (b) Since it's the sum.
