Answer 1

John's. Find the first common multiple of both denominators, in this case it's going to be ten, then the number you had to multiply to change these numbers to the common multiply you do to the numerators. so it works out like so:

Deena has a bottle of 4/10
John has a bottle of 25/10 or 2 1/2 (simplified)

Answer 2

johns water bottle can hold the most because 5/2=2 1/5
