1. Chocolate Chocolate Chocolate
2. Caramel Caramel Caramel
3. Chocolate Chocolate Caramel
4. Caramel Caramel Chocolate

The Average of Three

There are three numbers. The first two are 2/3 and 3/4.

What does the third number have to be to make the average of all three be 2?

4 7/12

In order for the average of three numbers to be 2, they must all add up to 6. That gives you this equation:
2/3 + 3/4 + n = 6

Solve for n = 55/12, or 4 7/12.
