Ответ:
[tex] \frac{5}{6} \times \frac{1}{5} = \frac{1}{6} \times \frac{1}{1} = \frac{1}{6} [/tex]
[tex] \frac{3}{7} \div \frac{9}{14} = \frac{3}{7} \times \frac{14}{7} = \frac{3}{1} \times \frac{2}{7} = \frac{6}{7} [/tex]
Приведем к общ. знаменателю:
[tex] \frac{1}{6} = \frac{1 \times 7}{6 \times 7} = \frac{7}{42} [/tex]
[tex] \frac{6}{7} = \frac{6 \times 6}{7 \times 6} = \frac{36}{42} [/tex]
И тут понятно что:
[tex] \frac{36}{42} > \frac{7}{42} [/tex]
