\frac{11200}{10000}=1+\frac{x}{100}
Divide both sides by 10000.
\frac{28}{25}=1+\frac{x}{100}
Reduce the fraction \frac{11200}{10000} to lowest terms by extracting and canceling out 400.
112=100+x
Multiply both sides of the equation by 100, the least common multiple of 25,100.
100+x=112
Swap sides so that all variable terms are on the left hand side.
x=112-100
Subtract 100 from both sides.
x=12
Subtract 100 from 112 to get 12.
