$\frac{1}{2}:\frac{5}{8} = \frac{1}{2} \times \frac{8}{5} = \frac{8}{{10}} = \frac{4}{5}$
$\frac{4}{5}:\frac{1}{6} = \frac{4}{5} \times \frac{6}{1} = \frac{{24}}{5}$
$\frac{{24}}{5}:\frac{3}{{10}} = \frac{{24}}{5} \times \frac{{10}}{3} = \frac{{240}}{{15}} = 16$
$16:\frac{1}{4} = 16 \times 4 = 64$
$64:\frac{3}{5} = 64 \times \frac{5}{3} = \frac{{320}}{3}$
$\frac{{320}}{3}:\frac{5}{{12}} = \frac{{320}}{3} \times \frac{{12}}{5} = 256$
