Answer 1

Ответ:

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

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

3) $\frac{1.7 - 2}{2 - 1.7} = \frac{ - 0.3}{0.3} = - 1$

4) $\frac{0.9 - 3}{3 - 0.9} = \frac{ - 2.1}{2.1} = - 1$
