Answer 1

Ответ:

4 4/9×(-1 1/8)=40/9×(-9/8)=-5

-5 5/6× 1 5/7=-35/6×12/7=-10

-6 3/4×(-1 11/45)=6 3/4×1 11/45=27/4×56/45=1 13/20

Answer 2

Пошаговое объяснение:

$4 \frac{4}{9} \times ( - 1 \frac{1}{8} ) = \frac{40}{9} \times ( - \frac{9}{8}) = - 5$

$- 5 \frac{5}{6} \times 1 \frac{5}{7} = - \frac{35}{6} \times \frac{12}{7} = - 10$

$- 6 \frac{3}{4} \times ( - 1 \frac{11}{45} ) = 6 \frac{3}{4} \times 1 \frac{11}{45} = \frac{27}{4} \times \frac{56}{45} = 1 \frac{13}{20}$
