Answer 1

Ответ:

10 4/7×(-2 11/12)=74/7×(-35/12)=-(185/6)=-30 5/6

7 5/9 *(-9 3/4)=68/9×(-39/4)=(-221/3)=(-73 2/3

Answer 2

Пошаговое объяснение:

$10 \frac{4}{7} \times ( -2 \frac{11}{12}) = \frac{74}{7} \times ( - \frac{35}{12} ) = (- \frac{185}{6} ) = - 30 \frac{5}{6}$

$7 \frac{5}{9} \times ( - 9 \frac{3}{4}) = \frac{68}{9} \times ( - \frac{39}{4} ) = ( - \frac{221}{3} ) = ( - 73 \frac{2}{3} )$
