Question

пожалуйста помогите ​

Answer 1

1.

$( - \frac{4}{5} ) \times ( - \frac{3}{8} ) \times ( - \frac{5}{12} ) = - \frac{4 \times 3 \times 5}{5 \times 8 \times 12} = - \frac{1 \times 1 \times 1}{1 \times 2 \times 4} = - \frac{1}{8}$

2.

$( - \frac{9}{10} ) \times \frac{5}{6} \times ( - \frac{2}{3} ) = \frac{9 \times 5 \times 2}{10 \times 6 \times 3} = \frac{3 \times 1 \times 1}{2 \times 3 \times 1} = \frac{3}{6} = \frac{1}{2}$

Answer 2

Ответ:

Пошаговое объяснение:

(-4/5)*(-3/8)*(-5/12)= - (4*3*5)/(5*8*12) = -1/8=-0.125;

(-9/10)*(5/6)*(-2/3) = (9*5*2)/(10*6*3)=1/2=0.5.
