Question

Elly poured 1/10 gallon of water into an empty bottle. now is 1/2 full. how many cups of water does a full bottle hold?

Answer 1

3.2 cups.

Explanation:

There are 16 cups in one gallon.

16 ÷ 10 = 1.6

Are 1.6 cups in 1/10 of a gallon. If the bottle is half full, that means we need to double this number(basically adding the two haves) to get the whole.

1.6 x 2 = 3.2

There is your answer. Let me know if you need anymore help!
