Answer 2

Пошаговое объяснение:

$\\ 1 \frac{8}{6} - \frac{1}{12 } = \frac{6 \times 1 + 8}{6} - \frac{1}{12} = \\ = \frac{6 + 8}{6} - \frac{1}{12} = \frac{14}{6} - \frac{1}{12} \\ = \frac{14 \times 2 - 1}{12} = \frac{28 - 1}{12} = \\ = \frac{27}{12} = \frac{27 \div 3}{12 \div 3} = \\ = \frac{9}{4} = 2 \frac{1}{4}$
