The simplified answer to this expression would be
If you are doing any scientific notation to the negative power the answer will be a decimal. In this case you will move the decimal point four places to the left.
The answer will be 0.0002077

x : 100%
Cross multiply: x=(275*100%)/12.5%=2200
Given that a square patio of at least 80 square feet is to be built from 125 tiles of length 12 inches or 1 feet.
Part A;
Since there are 125 tiles and the patio has a shape of a square of at least 80 square feet, then the possible dimensions of the patio are
9 ft by 9 ft = 81 ft
10 ft by 10 ft = 100 ft, and
11 ft by 11 ft = 121 ft.
Part B.
For a patio of dimensions, 9ft by 9ft, the number of tiles that will not be used is given by 125 - 81 = 44
For a patio of dimensions, 10ft by 10ft, the number of tiles that will not be used is given by 125 - 100 = 25
For a patio of dimensions, 11ft by 11ft, the number of tiles that will not be used is given by 125 - 121 = 4
