Answer:
The amount of cups of water in the water bottle is 7.5.
Explanation:
Given that Henry drank 2/5 of his bottle of water, and those 2/5 were distributed in 3 glasses, to determine the total amount of glasses that go into the bottle it is necessary to perform the following calculation:
2/5 X = 3
1/5 X = 1.5
X = 1.5 x 5
X = 7.5
Therefore, the bottle fits 7 and a half glasses of water.
