Помогите пж умоляю поздно приехал

А) $1 \frac{1}{6} \times 3 \frac{3}{7} = \frac{7}{6} \times \frac{24}{7} = \frac{24}{6} = 4$

Б) $2 \frac{4}{11} \div 2\frac{11}{14} = \frac{26}{11} \div \frac{39}{14} = \frac{26}{11} \times \frac{14}{39} = \frac{28}{33}$

В) $4 \frac{1}{5} \div 2 \frac{1}{10} \times 1 \frac{5}{6} = \frac{21}{5} \div \frac{21}{10} \times \frac{11}{6} = \\ = \frac{21 \times 10 \times 11}{5 \times 21 \times 6} = \frac{2 \times 11}{6} = \frac{22}{6} = \\ = \frac{11}{3} = 3 \frac{2}{3}$
