Пошаговое объяснение:

4/9 : 7/8 = 4/9 * 8/7 = 32/63

6/25 : 12/35 = 6/25 * 35/12 = 7/10

8/65 : 4/13 = 8/65 * 13/4 = 2/5

48/49 : 32/63 = 48/49 * 63/32 = 27/14 = 1 13/14

10 : 5/9 = 10 * 9/5 = 18

9/16 : 36 = 9/16 * 1/36 = 1/64

3 1/3 : 2 6/7 = 10/3 : 20/7 = 10/3 * 7/20 = 7/6 = 1 1/6

3 6/9 : 9/28 = 11/3 * 28/9 = 308/27 = 11 11/27

(5/9)x = 25

x = 25 * 9/5

x = 45

x : 8/25 = 5/32

x = 5/32 * 8/25

x = 1/20

(3 3/4)x - 1 2/3 = 2 11/12

(3 3/4)x = 2 11/12 + 1 2/3

(3 3/4)x = 2 11/12 + 1 8/12

(3 3/4)x = 3 19/12

x = 3 19/12 : 3 3/4

x = 55/12 * 4/15

x = 11/9

x = 1 2/9

5/7 : 4/5 = 5/7 * 5/4 = 25/28

6/35 : 18/49 = 6/35 * 49/18 = 7/15

27/28 : 9/56 = 27/28 * 56/9 = 6

28/45 : 63/40 = 28/45 * 40/63 = 32/81

6 : 2/7 = 6 * 7/2 = 21

7/25 : 28 = 7/25 * 1/28 = 1/100

2 2/3 : 2 2/7 = 8/3 * 7/16 = 7/6 = 1 1/6

4 4/9 : 5/27 = 40/9 * 27/5 = 24

(6/7)x = 24

x = 24 * 7/6

x = 28

x : 3/11 = 22/27

x = 22/27 * 3/11

x = 2/9

3 3/5 : x = 9/35

x = 3 3/5 : 9/35

x = 18/5 * 35/9

x = 14

(2 2/3)x - 1 5/7 = 3 1/21

(2 2/3)x = 3 1/21 + 1 5/7

(2 2/3)x = 3 1/21 + 1 15/21

(2 2/3)x = 4 16/21

x = 4 16/21 : 2 2/3

x = 100/21 * 3/8

x = 25/14

x = 1 11/14
