1) 13/17 + 5/16 + 7/16 = 13/17 + 12/16 = 13/17 + 3/4 = 52/68 + 51/68 = 103/68 = 1целая 35/68
2) (11/60 + 9/28) + ( 5/28 + 19/60) = 11/60 + 9/28 + 5/28 + 19/60 = 30/60 + 14/28 = 1/2 + 1/2 = 1
3) (5/8 + 19/36) - 1/36 = 5/8 + 19/36 - 1/36 = 5/8 + 18/36 = 5/8 + 1/2 = 5/8 + 4/8 = 9/8 = 1целая 1/8
4) (29/44 + 1/6) - 7/44 = 29/44 + 1/6 - 7/44 = 22/44 + 1/6 = 1/2 + 1/6 = 3/6 + 1/6 = 4/6 = 2/3
