\[\boxed{\mathbf{934\ (934)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[\textbf{а)} - \frac{4}{9}\ :4 = - \frac{4}{9}\ :\frac{4}{1} = - \left( \frac{4}{9} \bullet \frac{1}{4} \right) = - \frac{1}{9}\]

\[\textbf{б)} - \frac{3}{8}\ :( - 3) = - \frac{3}{8}\ :\left( - \frac{3}{1} \right) = + \left( \frac{3}{8} \bullet \frac{1}{3} \right) = \frac{1}{8}\]

\[\textbf{в)}\ 1\ :\left( - \frac{5}{7} \right) = - \left( 1 \bullet \frac{7}{5} \right) = - \frac{7}{5} = - 1,4\]

\[\textbf{г)} - \frac{2}{3}\ :( - 1) = + \left( \frac{2}{3} \bullet 1 \right) = \frac{2}{3}\]

\[\textbf{д)} - \frac{5}{7}\ :\frac{2}{7} = - \left( \frac{5}{7} \bullet \frac{7}{2} \right) = - \frac{5}{2} = - 2,5\]

\[\textbf{е)}\frac{11}{3}\ :\left( - \frac{5}{6} \right) = - \left( \frac{11}{3} \bullet \frac{6}{5} \right) = - \frac{22}{5} = - 4\frac{2}{5}\]
