1) 5/8 + 5/6 + 7/12 = 15/24 + 20/24 + 14/24 = 49/24 = 1 1/24
2) 1/5 + 3/8 - 2/9 = 72/360 + 135/360 - 80/360 = 127/360
3) 1/4 + 2/9 - 5/35 = 315/1260 + 140/1260 - 36/1260 = 419/1260
4) 3/4 + 4/5 + 1/20 = 15/20 + 16/20 + 1/20 = 32/20 = 8/5 = 1 3/5
5) 3/4 + 5/12 - 1/9 = 27/36 + 15/36 - 4/36 = 38/36 = 19/18 = 1 1/18
6) 4/15 + 2/5 + 7/10 = 8/30 + 12/30 + 21/30 = 41/30 = 1 11/30
