Ответ:

1.

$5 \frac{1}{4} \div \frac{7}{8} \times \frac{1}{5} = \frac{5 \times 4 + 1}{4} \times \frac{8}{7} \times \frac{1}{5} = \frac{21}{4} \times \frac{8}{7} \times \frac{1}{5} = \frac{6}{1} \times \frac{1}{5} = \frac{6}{5} = 1 \frac{1}{5}$

2.

$- 3 \frac{2}{3} \div \frac{5}{6} \times \frac{1}{11} = - \frac{3 \times 3 + 2}{3} \times \frac{6}{5} \times \frac{1}{11} = - \frac{11}{3} \times \frac{6}{5} \times \frac{1}{11} = - \frac{22}{5} \times \frac{1}{11} = - \frac{2}{5}$
