$\frac{\frac{a}{1}}{\frac{b}{c}}=$ $\frac{ac}{b}$

In division of two proper fractions, invert the divisor then proceed to multiplication.

$\dfrac{a}{\frac{b}{c}}=\dfrac{a}{1} \times \dfrac{c}{b}=\boxed{\dfrac{ac}{b}}$

$\dfrac{a}{\frac{b}{c}} = \color{#69047E}{\boxed{\dfrac{ac}{b}}}$ .

$\frac { a }{ { b }/c } =a\times \frac { { b }^{ -1 } }{ { c }^{ -1 } }$

$=\frac { ac }{ b }$
