Question

2. Emma knows that her mix of 5 cups of orange juice to 2 cups of ginger

ale will create enough drink for 7 people. If she is looking to create
enough drinks for 28 people, how many cups of orange juice will she
need? *

Answer 1

11 1 /2 ( 11 and a half)

Explanation:

If you noticed 7 and 2 are five numbers away.

To solve this I just added one to both of them until the sum was equal to 28.

If I had added one to 16 and 11, it would have given me 29, so I added a half.

That gave me 28.
