Выполним умножение дробей:

1. $$\frac{5}{6} \cdot \frac{4}{10} = \frac{5 \cdot 4}{6 \cdot 10} = \frac{20}{60} = \frac{1}{3}$$
2. $$\frac{11}{14} \cdot \frac{7}{22} = \frac{11 \cdot 7}{14 \cdot 22} = \frac{77}{308} = \frac{1}{4}$$
3. $$\frac{4}{15} \cdot \frac{5}{8} = \frac{4 \cdot 5}{15 \cdot 8} = \frac{20}{120} = \frac{1}{6}$$
4. $$\frac{3}{10} \cdot \frac{2}{6} = \frac{3 \cdot 2}{10 \cdot 6} = \frac{6}{60} = \frac{1}{10}$$
5. $$\frac{17}{33} \cdot \frac{11}{34} = \frac{17 \cdot 11}{33 \cdot 34} = \frac{187}{1122} = \frac{1}{6}$$

Ответ:
