\( \frac{9}{14} + \frac{2}{7} = \frac{9}{14} + \frac{2 \cdot 2}{7 \cdot 2} = \frac{9}{14} + \frac{4}{14} = \frac{9 + 4}{14} = \frac{13}{14} \)
\( \frac{3}{49} : \frac{13}{14} = \frac{3}{49} \cdot \frac{14}{13} \)
\( \frac{3}{7 \cdot 7} \cdot \frac{7 \cdot 2}{13} = \frac{3}{7} \cdot \frac{2}{13} \)
\( \frac{3 \cdot 2}{7 \cdot 13} = \frac{6}{91} \)
Ответ: 6/91
