Answer 1

Пошаговое объяснение:

$\frac{-3}{5}:\frac{5}{-9} = \frac{-3}{5} *\frac{-9}{5} = \frac{27}{25} \\\\\frac{16}{-25} :\frac{8}{-15} = \frac{16}{-25} *\frac{-15}{8} = \frac{-6}{-5} = \frac{6}{5} \\\\ \frac{9}{-10} :\frac{1}{2} = \frac{9}{-10} *\frac{2}{1} =\frac{9}{-5} = -\frac{9}{5} \\\\\frac{-3}{7} :\frac{5}{6} = \frac{-3}{7} *\frac{6}{5} = \frac{-18}{35}$
