Answer 1

$\displaystyle\bf\\1\frac{7}{8} :8\frac{1}{3} =x:\frac{4}{9} \\\\\\\frac{15}{8} :\frac{25}{3} =x:\frac{4}{9} \\\\\\\frac{25}{3} \cdot x=\frac{15}{8} \cdot \frac{4}{9} \\\\\\\frac{25}{3} \cdot x=\frac{5}{6} \\\\\\x=\frac{5}{6} :\frac{25}{3} =\frac{5}{6} \cdot\frac{3}{25} =\frac{1}{10} =0,1\\\\\\\boxed{x=0,1}$
