Пошаговое объяснение:
1)
|1/х| = 5/8
1)
1/х = 5/8
х = 1 : 5/8
х = 1 * 8/5
х1 = 8/5
х1 = 1. 3/5

2)
1/х = - 5/8
х = 1 : (-5/8)
х = 1 * (-8/5)
х2 = -8/5
х2 = -1. 3/5


2)
|1/у| = 2/7
1)
1/у = 2/7
у = 1 : 2/7
у = 1 * 7/2
у1 = 7/2
у1 = 3. 1/2

2)
1/у = -2/7
у = 1 : (-2/7)
у = 1 * (-7/2)
у2 = -7/2
у2 = -3. 1/2


3)
|1/z| = 2/5
1)
1/z = 2/5
z = 1 : 2/5
z = 1 * 5/2
z1 = 5/2
z1 = 2. 1/2

2)
1/z = -2/5
z = 1 : (-2/5)
z = 1 * (-5/2)
z2 = -5/2
z2 = -2. 1/2

4)
|2/х| = 1/3
1)
2/х = 1/3
х = 2 : 1/3
х = 2 * 3/1
х1 = 6/1
х1 = 6

2)
2/х = -1/3
х = 2 : (-1/3)
х = 2 * (-3/1)
х2 = -6/1
х2 = -6

5)
|3/у| = 5/6
1)
3/у = 5/6
у = 3 : 5/6
у = 3 * 6/5
у1 = 18/5
у1 = 3. 3/5

2)
3/у = -5/6
у = 3 : (-5/6)
у = 3 * (-6/5)
у2 = -18/5
у2 = -3. 3/5

6)
|4/х| = 8/9
1)
4/х = 8/9
х = 4 : 8/9
х = 4 * 9/8
х1 = 36/8
х1 = 4. 4/8
х1 = 4. 1/2

2)
4/х = -8/9
х = 4 : (-8/9)
х = 4 * (-9/8)
х2 = -36/8
х2 = -4. 4/8
х2 = -4. 1/2
