completely factor each numerator and denominator, then remember that division is multiplication by the reciprocal.

Yeah I did that but what is throwing me off is I know with dividing you flip the second expressions numerator and denominator to multiply them but do I flip the middle expression and the expression on the very right or just the middle one?

follow the order of operations ...

$\displaystyle \frac{a}{b} \div \frac{c}{d} \div \frac{e}{f}$

$\displaystyle \frac{a}{b} \times \frac{d}{c} \div \frac{e}{f}$

$\displaystyle \frac{ad}{bc} \div \frac{e}{f}$

$\displaystyle \frac{ad}{bc} \times \frac{f}{e}$
