Question

помогите пожалуйста с 512 номером

Answer 1

Пошаговое объяснение:

2/3 : (-2) = 2/3 * (-1/2) = -2/6 = -1/3

4 : (-1/2) = 4 * (-2/1) = -8/1 = -8

-5/6 : (-5/12) = -5/6 * (-12/5) = -1/1 * (-2/1) = 2/1 = 2

-4 2/3 : 2/9 = -14/3 * 9/2 = -7/1 * 3/1 = -21/1 = -21

5 : (-5/8) = 5 * (-8/5) = -40/5 = -8

-3 3/4 : 1 1/2 = -15/4 : 3/2 = -15/4 * 2/3 = -5/2 * 1/1 = -5/2 = -2 1/2

-6 1/4 : (-5/8) = -25/4 * (-8/5) = -5/1 * (-2/1) = 10/1 = 10

Answer 2

Решение:

$\frac{2}{3}:(-2)=-\frac{2}{3*2}=-\frac{1}{3}$

$4:(-\frac{1}{2})=-\frac{4}{\frac{1}{2} } =-\frac{4*2}{1} =-8$

$(-\frac{5}{6}):(-\frac{5}{12})=\frac{5*12}{6*5} =2$

$(-4\frac{2}{3} ):\frac{2}{9} =-\frac{14}{3}:\frac{2}{9}=-\frac{14*9}{3*2} =-7*3=-21$

$(-\frac{3}{4}):1\frac{1}{2}=-\frac{3}{4}:\frac{3}{2} =-\frac{3*2}{4*3}=-\frac{1}{2}$

$5:(-\frac{5}{8})=-\frac{5*8}{5}=-8$

$-3\frac{3}{4}:1\frac{1}{2}=-\frac{15}{4}:\frac{3}{2}=-\frac{15*2}{4*3}=-\frac{5}{2}=-2\frac{1}{2}$

$(-6\frac{1}{4}):(-\frac{5}{8})=\frac{25}{4}:\frac{5}{8}=\frac{25*8}{4*5}=5*2=10$
