Work Step by Step

$\displaystyle \frac{a-3}{16}\div\frac{a-3}{32}=\qquad$... apply property:$ \displaystyle \frac{P}{Q}\div\frac{R}{S}=\frac{P}{Q}\cdot\frac{S}{R} $ =$\displaystyle \frac{a-3}{16}\cdot\frac{32}{a-3}= \qquad$... apply property: $\displaystyle \frac{P}{Q}\cdot\frac{R}{S}=\frac{PR}{QS}$ $=\displaystyle \frac{(a-3)\cdot 16\cdot 2}{16(a-3)}\qquad$... reduce: 16, $(a-3)$ $=\displaystyle \frac{2}{1}$ $=2$
