Answer 3

Конечно, я помогу вам с вычислениями. Вот результаты:

1. $\frac{1}{2} \times 1 \frac{1}{3} = \frac{4}{6} \times \frac{4}{3} = \frac{16}{18} = \frac{8}{9}$.

2. $8 \times 1 \frac{7}{9} = 8 \times \frac{16}{9} = \frac{128}{9}$.

3. $1 \frac{1}{8} : \frac{3}{4} = \frac{8}{8} \times \frac{4}{3} = \frac{32}{24} = \frac{4}{3}$.

4. $\frac{2}{3} \times 1 \frac{8}{7} = \frac{2}{3} \times \frac{15}{7} = \frac{30}{21} = \frac{10}{7}$.

5. $\frac{5}{6} : 2 \frac{2}{9} = \frac{5}{6} \div \frac{20}{9} = \frac{5}{6} \times \frac{9}{20} = \frac{45}{120} = \frac{3}{8}$.

6. $3 \frac{1}{3} \times 2 = \frac{10}{3} \times 2 = \frac{20}{3}$.

7. $1 \frac{1}{9} \times 2 \frac{2}{5} = \frac{10}{9} \times \frac{12}{5} = \frac{120}{45} = \frac{8}{3}$.

8. $3 \frac{1}{2} : 1 \frac{1}{6} = \frac{7}{2} \div \frac{7}{6} = \frac{7}{2} \times \frac{6}{7} = 3$.

9. $3 \frac{1}{8} \times 2 = \frac{25}{8} \times 2 = \frac{50}{8} = \frac{25}{4}$.

10. $\frac{1}{6} \times 1 \frac{1}{3} = \frac{1}{6} \times \frac{4}{3} = \frac{4}{18} = \frac{2}{9}$
