3\7*(-1целых1\6)=

-1 целая 3\4:(-4 целых 3\8)=

Answer 1

$14 \frac{2}{3} - 20 \frac{3}{4} = - 20 \frac{3}{4} + 14 \frac{2}{3} = - 6 \frac{1}{12} \\ \frac{3}{7} \times ( - \frac{7}{6} ) = - \frac{1}{2} \\ - 1 \frac{3}{4} \div ( - 4 \frac{3}{8} ) = - \frac{7}{4} \div ( - \frac{8}{35} ) = \frac{7}{4} \times \frac{8}{35} = \frac{2}{5}$
