Answer 1

$x \div \frac{6}{7} = 1 \frac{1}{6} \div 3 \frac{1}{2} \\ \frac{7x}{6} = \frac{7}{6} \div \frac{7}{2} = \frac{7}{6} \times \frac{2}{7} = \frac{2}{6} = \frac{1}{3} \\ \frac{7x}{6} = \frac{1}{3} \\ x = \frac{1}{3} \div \frac{7}{6} = \frac{1}{3} \times \frac{6}{7} = \frac{2}{7}$

Ответ: х = 2/7.
