Question

4)4 2/3*(-3/14), 3) -7/8*1 1/7 2)-1,6*5/8 помогите решить

Answer 1

$4 \frac{2}{3} \times ( - \frac{3}{14} ) = - \frac{14 \times 3}{3 \times 14} = - 1 \\ - \frac{7}{8} \times 1 \frac{1}{7} = - \frac{7 \times 8}{8 \times 7} = - 1 \\ - 1.6 \times \frac{5}{8} = - \frac{16 \times 5}{10 \times 8} = - \frac{2}{2} = - 1$
