Решение:
- \( \frac{7}{7} = 1 \)
- \( \frac{1}{4} : \frac{1}{3} = \frac{1}{4} \times \frac{3}{1} = \frac{3}{4} \)
- \( \frac{3}{7} : \frac{1}{14} = \frac{3}{7} \times \frac{14}{1} = \frac{3 \times 14}{7} = 3 \times 2 = 6 \)
- \( \frac{6}{11} : \frac{6}{11} = 1 \)
- \( \frac{9}{13} : \frac{3}{13} = \frac{9}{13} \times \frac{13}{3} = \frac{9 \times 13}{13 \times 3} = \frac{9}{3} = 3 \)
- \( \frac{5}{7} : \frac{1}{7} = \frac{5}{7} \times \frac{7}{1} = 5 \)
