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)
$- frac{3}{8} times ( - frac{9}{10} ) = frac{27}{80}$
$frac{27}{80} div ( - frac{27}{32} ) = - frac{27}{80} times frac{32}{27} = - frac{4}{10} =$
$= - frac{2}{5}$
