Ответ:

1)

$- \frac{1}{8} \times( 8 \times ( - \frac{3}{11} )) = - \frac{1}{8} \times 8 \times ( - \frac{3}{11} ) = - 1 \times ( - \frac{3}{11} ) = \frac{3}{11}$

2)

$\frac{4}{5} \times 3 \frac{1}{3} \times ( - 7 \frac{1}{2} ) = \frac{4}{5} \times \frac{4}{3} \times ( - \frac{15}{2} ) = 4 \times 4 \times ( - \frac{1}{2} ) = - 8$

3)

$- \frac{5}{9} \times \frac{4}{7} \times ( - \frac{9}{5} ) = \frac{4}{7}$

4)

$\frac{4}{7} \times ( - \frac{5}{6} ) \times 21 = 4 \times ( - \frac{5}{6} ) \times 3 = 2 \times ( - 5) \times 1 = - 10$

5)

$2 \frac{1}{8} \times ( - \frac{3}{17} ) \times 16 = 2 \times ( - \frac{3}{17}) \times 2 = 4 \times ( - \frac{3}{17} ) - \frac{12}{17}$

6)

$- 8 \frac{2}{3} \times 1 \frac{2}{3} \times \frac{3}{5} = - \frac{26}{3} \times \frac{5}{3} \times \frac{3}{5} = - 8 \frac{2}{3}$
