Answer 1

а) -0.5 * (-0.18) = 0.09

б) -4 $\frac{1}{6}$ * 0.2 =  -4 $\frac{1}{6}$ * $\frac{1}{5}$ = - ($\frac{25}{6}$ * $\frac{1}{5}$ ) = - $\frac{5}{6}$

в) - 4$\frac{3}{8}$ : (-3$\frac{13}{16}$) = $\frac{35}{8}$ : $\frac{45}{16}$ = $\frac{35}{8}$ * $\frac{16}{45}$ =  7 * $\frac{2}{9}$ = $\frac{14}{9}$ = 1 $\frac{5}{9}$

г) $\frac{- 0.3}{0.75}$ = - $\frac{1}{2,5}$ = - 0.4
