6b=5-\frac{5}{4}
Subtract \frac{5}{4} from both sides.
6b=\frac{20}{4}-\frac{5}{4}
Convert 5 to fraction \frac{20}{4}.
6b=\frac{20-5}{4}
Since \frac{20}{4} and \frac{5}{4} have the same denominator, subtract them by subtracting their numerators.
6b=\frac{15}{4}
Subtract 5 from 20 to get 15.
b=\frac{\frac{15}{4}}{6}
Divide both sides by 6.
b=\frac{15}{4\times 6}
Express \frac{\frac{15}{4}}{6} as a single fraction.
b=\frac{15}{24}
Multiply 4 and 6 to get 24.
b=\frac{5}{8}
Reduce the fraction \frac{15}{24} to lowest terms by extracting and canceling out 3.
