1) 3/8 + 2/9 = 27/72 + 16/72 = 43/72
7/12 + 3/8 = 14/24 + 9/24 = 23/24
3/7 + 5/14 = 6/14 + 5/14 = 11/14
1/6 + 2/15 = 5/30 + 4/30 = 9/30 = 3/10
2) 3/4 + 5/14 = 21/28 + 10/28 = 31/28 = 1 3/28
4/9 + 11/15 = 20/45 + 33/45 = 53/45 = 1 8/45
7/10 + 12/25 = 35/50 + 24/50 = 59/50 = 1 9/50
3/5 + 6/7 = 21/35 + 30/35 = 51/35 = 1 16/35
3) 7/12 - 2/9 = 21/36 - 8/36 = 13/36
13/15 - 1/2 = 26/30 - 15/30 = 11/30
9/20 - 11/30 = 27/60 - 22/60 = 5/60 = 1/12
59/100 - 6/25 = 59/100 - 24/100= 35/100 = 7/20
4) 11/16 - 7/12 = 44/48 - 28/48 = 16/48 = 1/3
6/7 - 3/11 = 66/77 - 21/77 = 45/77
23/24 - 7/18 = 69/72 - 28/72 = 41/72
17/28 - 5/14 = 17/28 - 10/28 = 7/28 = 1/4
