Answer 1

$8 \frac{1}{6} : 1\frac{1}{6} - 6 \frac{2}{3} = \frac{49}{6} * \frac{6}{7} - 6 \frac{2}{3} = \frac{7}{6} * 6 - 6 \frac{2}{3} = 7 - \frac{20}{3} = \frac{21}{3} - \frac{20}{3} = \frac{1}{3}$

Answer 2

$8 \frac{1}{6} \div 1 \frac{1}{6} - 6 \frac{2}{3} = \frac{49}{6} \times \frac{6}{7} - 6 \frac{2}{3} = \frac{49}{7} - \frac{20}{3} = 7 - \frac{20}{3} = \\ = \frac{21}{3} - \frac{20}{3} = \frac{1}{3}$
