1. 3 1/5 + 3 = 16/5 + 3/1 = 16/5 + 15/5 = 31/5...

2. 19/20 + 8/15 = 57/60 + 32/60 = 89/60..

3. 26/8 + 12/8 = 38/8 = 19/4...

4. 1/3 + 6/15 = 5/15 + 6/15 = 11/15..

5. 44/10 + 3/4 = 176/40 + 30/40 = 196/40 = 49/10.

6. 6/12 - 3/12 = 3/12..

8. 15/6 - 3/6 = 13/6...

9. 3/8 × 16/5 = 48/40 = 6/5..

10. 1/3 × 6/15 = 6/45 = 2/15..

15. 3/8 × 1/4 = 3/32......
