Answer 1

Ответ:

$\frac{3}{ - 1} = - 3 \\ 3 - \frac{1}{ - 1} = 3 + 1 = 4 \\ \frac{3 - 1}{3} = \frac{2}{3}$

$\frac{ - 0.5}{ - \frac{1}{3} } = \frac{1}{2} \div \frac{1}{3} = \frac{1}{2} \times \frac{3}{1} = \frac{3}{2} = 1 \frac{1}{2} \\ - 0.5 - ( - \frac{1}{ \frac{1}{3} } ) = - 0.5 + 3 = 2.5 \\ \frac{ - 0.5 - \frac{1}{3} }{ - 0.5} = - \frac{5}{6} \div ( - \frac{1}{2} ) = \frac{5}{6} \times \frac{2}{1} = \frac{5}{3} = 1 \frac{2}{3}$
