x-1=\frac{110}{100}
Divide both sides by 100.
x-1=\frac{11}{10}
Reduce the fraction \frac{110}{100} to lowest terms by extracting and canceling out 10.
x=\frac{11}{10}+1
Add 1 to both sides.
x=\frac{11}{10}+\frac{10}{10}
Convert 1 to fraction \frac{10}{10}.
x=\frac{11+10}{10}
Since \frac{11}{10} and \frac{10}{10} have the same denominator, add them by adding their numerators.
x=\frac{21}{10}
Add 11 and 10 to get 21.
