Question

(5/6-2/3)*(7/8-1/2(*(-4)=помогите решить•>•​

Answer 1

Ответ:

((5-4) /3) *(7-4/8)*-4= 1*3/6*8 * (-4) = 1/2 * -1/2 = -1/4

Answer 2

Пошаговое объяснение:

$1) \frac{1}{2} \times - 4 = - \frac{4}{2} = - \frac{2 \times 2}{1 \times 2} = - 2$

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

$3) \frac{7}{8} - - 2 = \frac{23}{8} = 2 \frac{7}{8}$

$4) \frac{1}{6} \times 2 \frac{7}{8} = \frac{1}{6} \times \frac{23}{8} = \frac{1 \times 23}{6 \times 8} = \frac{23}{48}$

Ответ:

$\frac{23}{48}$
