10 : $\frac{5}{9}$ = $\frac{10}{1} : \frac{5}{9} = \frac{10}{1} * \frac{9}{5} = 18$

1 : $\frac{8}{13}$ = $\frac{13}{13} : \frac{8}{13} = \frac{13}{13} * \frac{13}{8} = \frac{13}{8} = 1\frac{5}{8} = 1,625$

$\frac{9}{16}$ : 36 = $\frac{9}{16} : \frac{36}{1} = \frac{9}{16} * \frac{1}{36} = \frac{1}{64} = 0,015625$

$2\frac{13}{16}$ : $4\frac{3}{8}$ = $\frac{45}{16} : \frac{35}{8} = \frac{45}{16} * \frac{8}{35} = \frac{9}{14}$
