Answer 1

в)

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

г)

$-1\frac{7}{8} +2\frac{1}{4} =-\frac{15}{8} +\frac{9}{4}= -\frac{15}{8}+\frac{18}{8} =\frac{3}{8}$

Answer 2

Ответ:

в)

$\frac{1}{6} - \frac{2}{3} = \frac{1}{6} - \frac{4}{6} = - \frac{3}{6} = - \frac{1}{2} = - 0.5$

г)

$- 1 \frac{7}{8} + 2 \frac{1}{4} = \frac{18}{8} - \frac{15}{8} = \frac{3}{8} = 0.375$
