Решение:
- 1) \( 10 : \frac{5}{9} = 10 \times \frac{9}{5} = \frac{10 \times 9}{5} = 2 \times 9 = 18 \)
- 2) \( 1 : \frac{8}{13} = 1 \times \frac{13}{8} = \frac{13}{8} \)
- 3) \( \frac{9}{16} : 36 = \frac{9}{16} \times \frac{1}{36} = \frac{9 \times 1}{16 \times 36} = \frac{1}{16 \times 4} = \frac{1}{64} \)
Ответ: 1) 18 2) \( \frac{13}{8} \) 3) \( \frac{1}{64} \)
