## Thinking Mathematically (6th Edition)

Two rational numbers of the form $\frac{a}{b}$and $\frac{c}{d}$ can be multiplied by dividing the product of numerators from the product of denominators. This can be shown as follows: $\frac{a}{b}\times \frac{c}{d}=\frac{a\cdot c}{b\cdot d}$ The product of the two rational numbers thus gives: $\frac{5}{6}\cdot \frac{1}{2}=\frac{5}{12}$
