Answer 2

Sure, I'd be happy to help you with these calculations:

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 = 1/28 + 10/28 = 11/28

5. 14/15 - 7/10 = 28/30 - 21/30 = 7/30

6. 3/8 + 1/6 = 9/24 + 4/24 = 13/24
