Help please just answer would be fine

The amount of water decreases 16\frac{1}{2} pints in 12 weeks.

Solution:

The amount of water decreases in 7 weeks = 9\frac{5}{8} pints

The amount of water decreases each week is same.

Let us first change the mixed fraction into improper fraction.

9\frac{5}{8} pints = \frac{(9\times8)+5}{8}

             =\frac{77}{8} pints

The amount of water decreases in 1 week

              $=\frac{\frac{77}{8} }{7}

              =\frac{77}{8\times7}

              =\frac{11}{8}

So, the amount of water decreases in 1 week is \frac{11}{8} pints.

The amount of water decreases in 12 week

               =\frac{11}{8}\times12

               =\frac{132}{8}

               =16\frac{4}{8}

               =16\frac{1}{2} pints

Hence the amount of water decreases 16\frac{1}{2} pints in 12 weeks.
