Пошаговое объяснение:

1)

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

2)

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

3)

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

4)

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

5)

-3/4 : 1. 1/2 = -3/4 : 3/2 =

-3/4 * 2/3 = -2/4 = -1/2

6)

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

7)

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

8)

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

Answer 2

Ответ:

ниже

Пошаговое объяснение:

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

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

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

5 : $(-\frac{5}{8})$ = -5 : $\frac{5}{8}$ = $-\frac{5}{1} * \frac{8}{5} = -8$

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

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

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

$(-6\frac{1}{4}) : (-\frac{5}{8}) = \frac{25}{4} : \frac{5}{8} = \frac{24}{4} * \frac{8}{5} = 10$
