p=\frac{7}{12}-\frac{5}{12}
Subtract \frac{5}{12} from both sides.
p=\frac{7-5}{12}
Since \frac{7}{12} and \frac{5}{12} have the same denominator, subtract them by subtracting their numerators.
p=\frac{2}{12}
Subtract 5 from 7 to get 2.
p=\frac{1}{6}
Reduce the fraction \frac{2}{12} to lowest terms by extracting and canceling out 2.
