Ответ:

$1)2 \frac{2}{11} \times \frac{7}{8} \div \frac{7}{11} = \frac{24}{11} \times \frac{7}{8} \div \frac{7}{11} = \frac{21}{11} \times \frac{11}{7} = 3$

$3 \frac{2}{3} \times 4 \frac{7}{8} \div \frac{13}{16} = \frac{11}{3} \times \frac{39}{8} \times \frac{16}{13} = \frac{11}{3} \times 6 = 22$

$3)1 \frac{1}{3} \times 2 \frac{2}{3} \div \frac{4}{9} = \frac{4}{3} \times \frac{8}{3} \times \frac{9}{4} = \frac{32}{9} \times \frac{9}{4} = 8$

$4)6 \frac{4}{15} \times \frac{1}{2} \div 3 \frac{2}{15} = \frac{94}{15} \times \frac{1}{2} \times \frac{15}{47} = \frac{1}{2} \times 2 = 1$

$5)8 \frac{1}{3} \times 1 \frac{5}{7} \div 2 \frac{8}{21} = \frac{25}{3} \times \frac{12}{7} \times \frac{21}{50} = \frac{12}{7} \times \frac{7}{2} = 6$

$6)1 \frac{5}{6} \times 3 \frac{3}{5} \div 2 \frac{1}{5} = \frac{11}{6} \times \frac{18}{5} \times \frac{5}{11} = \frac{18}{5} \times \frac{5}{6} = 3$
