Question

You are thirsty, so a friend has offered to give you 50% of his water. What information must you have in order to find out how much water your friend will give you?

Answer 1

How much water he has.

Explanation:

All you need to solve this is the amount of water that your friend has.

You can use an equation, where `f` is the amount of water that your friend has and `w` is the amount of water you'd get:

`1/2f=w`
