Объяснение:

$\frac{5}{9}x = 1\frac{1}{3}$
$\frac{5}{9} x = \frac{4}{3}$
$\frac{5}{9} x = \frac{12}{9}$
$x = \frac{12}{9}/\frac{5}{9}$
$x=\frac{12}{9}*\frac{9}{5}$
$x=\frac{12}{5} = 2\frac{2}{5} = 2.4$
_______________

$5x = \frac{10}{13}$
$x = \frac{10}{13} / 5$
$x = \frac{10}{13} / \frac{65}{13}$
$x = \frac{10}{13} * \frac{13}{65}$

$x = \frac{10}{65} = \frac{2}{13}$
____________

$\frac{7}{12} /x = \frac{3}{4}$
$x =\frac{7}{12}/\frac{3}{4}$
$x = \frac{7}{12}/\frac{9}{12} = \frac{7}{12}*\frac{12}{9} = \frac{7}{9}$
___________________

$1\frac{4}{5} /x = 3\frac{3}{5}$
$x=1\frac{4}{5} /3\frac{3}{5} = \frac{9}{5} /\frac{18}{5} = \frac{9}{5}*\frac{5}{18} = \frac{1}{2} = 0.5$
