The amount of water decreases pints in 12 weeks.
Solution:
The amount of water decreases in 7 weeks = pints
The amount of water decreases each week is same.
Let us first change the mixed fraction into improper fraction.
pints =
pints
The amount of water decreases in 1 week
So, the amount of water decreases in 1 week is pints.
The amount of water decreases in 12 week
pints
Hence the amount of water decreases pints in 12 weeks.

Step-by-step explanation:
88 can be rewritten as 8 x 10 and 8 can be rewritten as making a 2 come out of the root.
10 can be rewritten as 2 x 5.
2*2 can also be rewritten as making a 2 come out of the root.
We can't keep simplifying the root.
