а) 8 9/14 + 3 3/7 = (8 + 3) + (9/14 + 3/7) = 11 + (63/14 + 6/14) = 11 + 69/14 = 11 11/14
б) 12 11/12 + 13/18 = (12 + 0) + (11/12 + 13/18) = 12 + (99/72 + 52/72) = 12 + 151/72 = 12 151/72 = 14 7/72
в) 7 5/12 - 3 7/24 = (7 - 3) + (5/12 - 7/24) = 4 + (10/24 - 7/24) = 4 + 3/24 = 4 + 1/8 = 4 1/8
г) 12 7/9 - 8 2/15 = (12 - 8) + (7/9 - 2/15) = 4 + (105/135 - 18/135) = 4 + 87/135 = 4 87/135
д) 24 11/16 - 17 1/6 = (24 - 17) + (11/16 - 1/6) = 7 + (99/96 - 16/96) = 7 + 83/96 = 7 83/96
е) 8 23/30 - 7 11/20 = (8 - 7) + (23/30 - 11/20) = 1 + (46/60 - 33/60) = 1 + 13/60 = 1 13/60
ж) 4 3/16 - 5/8 = (4 - 0) + (3/16 - 10/16) = 4 + (-7/16) = 4 - 7/16 = 3 9/16
з) 6 4/9 - 3 7/5 = (6 - 3) + (4/9 - 35/9) = 3 + (-31/9) = 3 - 31/9 = 2 8/9
и) 10 3/24 - 9 19/36 = (10 - 9) + (3/24 - 19/36) = 1 + (9/72 - 38/72) = 1 + (-29/72) = 1 - 29/72 = 43/72
к) 22 10/51 - 18 2/34 = (22 - 18) + (10/51 - 2/34) = 4 + (680/1734 - 102/1734) = 4 + 578/1734 = 4 578/1734 = 4 17/289
л) 14 4/19 - 13 1/8 = (14 - 13) + (4/19 - 1/8) = 1 + (32/152 - 19/152) = 1 + 13/152 = 1 13/152
м) 62 9/11 - 45 1/22 = (62 - 45) + (9/11 - 1/22) = 17 + (198/242 - 11/242) = 17 + 187/242 = 17 187/242
