Answer 1

1) 1/4 + 3/5 = 5/20 + 12/20 = 17/20 
2) 9/11 - 2/5 = 45/55 - 22/55 = 23/55
3) 13/16 - 9/32 = 26/32 - 9/32 = 17/32
4) 3/28 + 5/14 = 3/28 + 10/28 = 13/28
5) 14/15 - 7/10 = 28/30 - 21/30 = 7/30
6) 3/8 + 1/6 = 9/24 + 4/24 = 13/24
7) 9/25 - 7/20 = 36/100 - 35/100 = 1/100
8) 37/42 - 17/24 = 148/168 - 119/168 = 29/168
9) 11/24 - 3/16 = 22/48 - 9/48 = 13/48
10) 9/16 + 7/24 - 3/8 = 27/48 + 14/48 - 18/48 = 23/48
11) 1/3 - 1/6 + 1/4 = 4/12 - 2/12 + 3/12 = 5/12
12) 2/5 + 4/15 - 5/9 = 18/45 + 12/45 - 25/45 = 5/45 = 1/9
