Answer 2

Ответ:

$1) \: 1 \frac{1}{2} \times 1 \frac{1}{3} \times 1 \frac{1}{4} \times 1\frac{1}{5} \times 1 \frac{1}{6} - \frac{1}{2} = \frac{3}{2} \times \frac{4}{3} \times \frac{5}{4} \times \frac{6}{5} \times \frac{7}{6} - \frac{1}{2} = \frac{7}{2} - \frac{1}{2} = \frac{6}{2} = 3$

$2) \: 1 \frac{1}{4} \times 1\frac{1}{5} \times 1\frac{1}{6} \times 1 \frac{1}{7} \times 1 \frac{1}{8} - \frac{1}{4} = \frac{5}{4} \times \frac{6}{5} \times \frac{7}{6} \times \frac{8}{7} \times \frac{9}{8} - \frac{1}{4} = \frac{9}{4} - \frac{1}{4} = \frac{8}{4} = 2$
