Пошаговое объяснение:

№1

1) 1 4/15 + 6 13/45 = 1 12/45 + 6 13/45 = 7 25/45 = 7 5/9

2) 7 5/9 - 7/12 = 7 20/36 - 21/36 = 6 56/36 - 21/36 = 6 35/36

№2

1) 6/7 - 3/14 = 12/14 - 3/14 = 9/14

2) 10 5/28 + 9/14 = 10 5/28 + 18/28 = 10 23/28

№3

1) 8 7/12 - 5/18 = 8 42/72 - 20/72 = 8 22/72 = 8 11/36

2) 8 11/36 + 1 3/4 = 8 11/36 + 1 27/36 = 9 38/36 = 10 2/36 = 10 1/18

3) 10 1/18 - 2 1/6 = 10 1/18 - 2 3/18 = 9 19/18 - 2 3/18 = 7 16/18 = 7 8/9
