Find the quotient:

$\dfrac{-12}{7} \div (-16)$

Find the quotient:

$-9 \div \left(\dfrac{-5}{18}\right)$

Name the property of multiplication illustrated by the following statement:

$\left(\dfrac{-3}{4} \times \dfrac{5}{7}\right) \times \dfrac{-9}{11} = \dfrac{-3}{4} \times \left(\dfrac{5}{7} \times \dfrac{-9}{11}\right)$

Name the property of multiplication illustrated by the following statement:

$\dfrac{-2}{3} \times \left(\dfrac{-5}{6} + \dfrac{7}{8}\right) = \left(\dfrac{-2}{3} \times \dfrac{-5}{6}\right) + \left(\dfrac{-2}{3} \times \dfrac{7}{8}\right)$
