37*(-1целых16)=

-1 целая 34:(-4 целых 38)=

Answer 1

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