помогите!!!!!!!!!!!!!!!!!!

Answer 1

$\displaystyle 8\frac{1}{13}:(\frac{9}{13}-1)-4*4\frac{1}{2}=\frac{105}{13}:(-\frac{4}{13})-4*\frac{9}{2}=-\frac{105}{13}*\frac{13}{4}-2*9=-105*\frac{1}{4}-18=\\\\-\frac{105}{4}-18=-\frac{177}{4}=-44\frac{1}{4}$

Answer 2

Ответ:

-44,25

Пошаговое объяснение:

1) 9/13 - 1 = 9/13 - 13/13 = -4/13

2) 8. 1/13 : (-4/13) = 105/13 * (-13/4) = -105/4 = -26,25

3) 4 * 4. 1/2 = 4 * 9/2 = 36/2 = 18

4) -26,25 - 18 = -44,25
