Пошаговое объяснение:

№1

1) 1/6 + 1/8 = 4/24 + 3/24 = 7/24

2) 7/24 * 4/7 = 1/6 * 1/1 = 1/6

№2

1) 2/3 - 1/9 = 6/9 - 1/9 = 5/9

2) 5/9 : 5/6 = 5/9 * 6/5 = 1/3 * 2/1 = 2/3

№3

4 1/4* 1 3/5 : 3 2/5 = 17/4 * 8/5 : 17/5 =

17/1 * 2/5 * 5/17 = 17/1 * 2/1 * 1/17 = 1/1 * 2/1 * 1/1 =

2/1 = 2

№4

1) 2 7/8 * 5 1/3 : 3 5/6 = 23/8 * 16/3 : 23/6 =

23/1 * 2/3 * 6/23 = 1/1 * 2/1 * 2/1 = 4/1 = 4

№5

1) 4 2/3 * 10 1/2 = 14/3 * 21/2 = 7/1 * 7/1 = 49/1 = 49

2) 9 4/5 : 49 = 49/5 * 1/49 = 1/5 * 1/1 = 1/5

№6

1) 4/5 - 7/20 = 16/20 - 7/20 = 9/20

2) 6 2/3 : 9/20 = 20/3 * 20/9 = 400/27 = 14 22/27
