18. Найдите частное:

Решение:

1. \( \frac{5}{8} : 10 = \frac{5}{8} \cdot \frac{1}{10} = \frac{1}{8} \cdot \frac{1}{2} = \frac{1}{16} \)
2. \( \frac{3}{5} : 18 = \frac{3}{5} \cdot \frac{1}{18} = \frac{1}{5} \cdot \frac{1}{6} = \frac{1}{30} \)
3. \( \frac{14}{18} : 28 = \frac{14}{18} \cdot \frac{1}{28} = \frac{1}{18} \cdot \frac{1}{2} = \frac{1}{36} \)
4. \( 4 : \frac{8}{9} = 4 \cdot \frac{9}{8} = \frac{1}{1} \cdot \frac{9}{2} = \frac{9}{2} \)
5. \( 32 : \frac{24}{8} = 32 : 3 = \frac{32}{3} \)
6. \( 14 : \frac{7}{8} = 14 \cdot \frac{8}{7} = 2 \cdot 8 = 16 \)

Ответ: 1) \( \frac{1}{16} \) 2) \( \frac{1}{30} \) 3) \( \frac{1}{36} \) 4) \( \frac{9}{2} \) 5) \( \frac{32}{3} \) 6) 16
