Find the quotient:

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

To divide one rational number by another, multiply the dividend by the reciprocal of the divisor.

Dividing,

$\dfrac{-12}{7} \div (-16) = \dfrac{-12}{7} \div \dfrac{-16}{1} \\[1em] = \dfrac{-12}{7} \times \dfrac{1}{-16} \\[1em] = \dfrac{(-12) \times 1}{7 \times (-16)} \\[1em] = \dfrac{-12}{-112} = \dfrac{3}{28}$

Hence, $\mathbf{\dfrac{-12}{7} \div (-16) = \dfrac{3}{28}}$.
