# How does the division of rational expressions differ from the multiplication of rational expressions?

Oct 26, 2014

Multiplication

$\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}$

Division

$\frac{a}{b} \div i \mathrm{de} \frac{c}{d} = \frac{a}{b} \cdot \frac{d}{c} = \frac{a \cdot d}{b \cdot c}$

I hope that this was helpful.
