Answer 1

1) 1/5 + 1/9 + 1/3 = 9/45 + 5/45 + 15/45 = 29/45
2) 1/2 + 3/5 - 2/3 = 15/30 + 18/30 - 20/30 = 13/30
3) 5/6 + 3/8 - 1/4 = 20/24 + 9/24 - 6/24 = 23/24
4) 5/9 + 1/6 + 3/4 = 20/36 + 6/36 + 27/36 = 53/36 = 1 17/36
5) 1/3 + 4/9 + 5/6 = 18/54 + 24/54 + 45/54 = 87/54 = 1 33/54
6) 1/4 + 1/5 - 3/10 = 5/20 + 4/20 - 6/20 = 3/20
