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)
ratio of perimeter is the same as ratio of sides so perimeter would be 1:4
since area is in square units you need to square the ratio (1:4)^2 which is 1:16
1 foot and 6 inches is the answer. Subtract the highest from the lowest #.
