9-154.

Simplify each expression.

1. $\frac { 12 } { 5 } \div \frac { 7 } { 10 }$

Dividing by a fraction is the same as multiplying by its reciprocal.

$\frac{12}{5}\left(\frac{10}{7}\right)$

Simplifying at the beginning is easier than simplifying after multiplying.

$\frac{12}{1}\left(\frac{2}{7}\right)$

$\frac{24}{7}$

1. $\frac{9}{4}\div\left(-\frac{1}{3}\right)$

See the help for part (a).

$-\frac{27}{4}$

1. $-\frac{3}{5}\div\left(-\frac{1}{6}\right)$
