Question

пожалуйста помогите срочно

Answer 1

1)
$- \frac{8}{15} \times ( - \frac{14}{15} ) = \frac{112}{225}$
$\frac{112}{225} \div ( - \frac{16}{25} ) = \frac{112}{225} \times \frac{25}{16} = - \frac{7}{9}$
2)
$- \frac{3}{8} \times ( - \frac{9}{10} ) = \frac{27}{80}$
$\frac{27}{80} \div ( - \frac{27}{32} ) = - \frac{27}{80} \times \frac{32}{27} = - \frac{4}{10} =$
$= - \frac{2}{5}$
