Ответ...................

Answer 2

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