Rounding to the nearest 10:

Rule: Look at the ones digit.
- If it’s 5 or more, round up.
- If it’s less than 5, round down.

1. 65 → ones digit is 5 → round up → 70
2. 56 → ones digit is 6 → round up → 60
3. 32 → ones digit is 2 → round down → 30
4. 81 → ones digit is 1 → round down → 80
5. 28 → ones digit is 8 → round up → 30
6. 30 → already a multiple of 10 → 30
7. 49 → ones digit is 9 → round up → 50
8. 19 → ones digit is 9 → round up → 20
9. 42 → ones digit is 2 → round down → 40
10. 37 → ones digit is 7 → round up → 40
11. 12 → ones digit is 2 → round down → 10
12. 63 → ones digit is 3 → round down → 60
13. 96 → ones digit is 6 → round up → 100
14. 45 → ones digit is 5 → round up → 50
15. 74 → ones digit is 4 → round down → 70

Rounding to the nearest 100:

Rule: Look at the tens digit.
- If it’s 5 or more, round up.
- If it’s less than 5, round down.

17. 485 → tens digit is 8 → round up → 500
18. 296 → tens digit is 9 → round up → 300
19. 704 → tens digit is 0 → round down → 700
20. 239 → tens digit is 3 → round down → 200
21. 672 → tens digit is 7 → round up → 700
22. 593 → tens digit is 9 → round up → 600
23. 562 → tens digit is 6 → round up → 600
24. 925 → tens digit is 2 → round down → 900
25. 846 → tens digit is 4 → round down → 800
26. 749 → tens digit is 4 → round down → 700
27. 365 → tens digit is 6 → round up → 400
28. 183 → tens digit is 8 → round up → 200
29. 133 → tens digit is 3 → round down → 100
