To solve all of these, you need to find a common denominator and simplify, (1) 8/28 + 14/28 = 22/28 = 11/14 (2) 14/18 + 9/18 = 23/18 = 1 5/18 (3) 6/18 + 6/18 = 12/18 = 2/3 (4) 10/30 + 12/30 = 22/30 =11/15 (5) 8/12 + 3/12 = 11/12 (6) 32/48 + 20/48 = 52/48 = 1 1/12 (7) 12/21 + 7/21 = 19/21 (8) 40/50 + 40/50 = 80/50 = 1 3/5 (9) 12/18 + 15/18 = 27/18 = 1 1/2 (10) 12/27 + 9/27 = 21/27 (11) 40/50 + 20/50 = 60/50 = 1 1/5

The answer to your question is 1/9
