1. 10/12 - 2/3 = 10/12 - 8/12 = 2/12 = 1/6

2. 11/12 - 1/3 = 11/12 - 4/12 = 7/12

3. 1/2 - 2/5 = 5/10 - 4/10 = 1/10

4. 1/6 + 3/5 = 5/30 + 18/30 = 23/30

5. 5/8 + 1/2 = 5/8 + 4/8 = 9/8 = 1 1/8

6. 5/16 + 3/4 = 5/16 + 12/16 = 17/16 = 1 1/16

7. 2/4 - 9/20 = 10/20 - 9/20 = 1/20

8. 12/28 + 11/35 = 60/140 + 44/140

= 104/140 = 26/35

9. 9/ + 1/ = hindi po kumpleto ang tanong huhu
