Answer 1

Ответ:

$m - n = 0.6$

$1) \: \frac{2(m - n)}{3} = \frac{2 \times 0.6}{3} = \frac{1.2}{3} = 0.4$

$2) \: \frac{n - m}{0.4} = - \frac{m - n}{0.4} = - \frac{0.6}{0.4} = - \frac{6}{10} \times \frac{10}{4} = - \frac{6}{4} = - 1.5$

$3) \: \frac{1.5}{m - n} = \frac{1.5}{0.6} = \frac{15}{10} \times \frac{10}{6} = \frac{15}{6} = 2.5$

$4) \: \frac{m - n}{n - m} = - \frac{m - n}{m - n} = - \frac{0.6}{0.6} = - 1$
