Answer
$\dfrac{7}{5}$
Work Step by Step
RECALL:
$\dfrac{a}{b} \div \dfrac{c}{d} = \dfrac{a}{b} \cdot \dfrac{d}{c}$
Use the rule above to obtain:
$\\=\dfrac{7}{9} \cdot \dfrac{9}{5}$
Cancel the common factors to obtain:
$\require{cancel}
\\=\dfrac{7}{\cancel{9}} \cdot \dfrac{\cancel{9}}{5}
\\=\dfrac{7}{5}$
