Пошаговое объяснение:

1) 1/5 + 3/8 - 2/9 = 72/360 + 135/360 - 80/360 =

(72+135-80)/360 = 127/360

2) 1/4 + 5/12 - 1/9 = 9/36 + 15/36 - 4/36 =

(9+15-4)/36 = 20/36 = 5/9

1) 2 7/17 + 4 6/17 = (2+4) + (7+6)/17 = 6 + 13/17 = 6 13/17

2) (6 2/15 + 9 4/25) - 11 2/5 = (6 10/75 + 9 12/75) - 11 30/75 = 15 22/75 - 11 30/75 = 14 97/75 - 11 30/75 = 3 67/75

3) 8 - 5 3/9 = 7 9/9 - 5 3/9 = 2 6/9 = 2 2/3
