Question

4/5×3 1/3×(-7 1/2) Пж​

Answer 1

Ответ:

$\frac{4}{5} \times 3 \frac{1}{3} \times ( - 7 \frac{1}{2}) = -20 \\1) \frac{4}{5} \times 3 \frac{1}{3} = \frac{4}{5} \times \frac{10}{3} = \frac{40}{15} = 2 \frac{2}{3} \\ 2)2 \frac{2}{3} \times ( - 7 \frac{1}{2}) = \frac{8}{3} \times ( - \frac{15}{2}) = - \frac{120}{6} = -20$
