Rounding Numbers worksheet for practicing rounding to the nearest 10.

Let's solve the problem step by step.

🔢 Task: Round each number to the nearest 10

To round a number to the nearest 10:
- Look at the ones digit (the last digit).
- If it is 5 or greater, round up.
- If it is less than 5, round down.

✔ Solutions with Explanation

We'll go through each number:

1. 49 → ones digit is 9 → ≥ 5 → round up → 50
2. 97 → ones digit is 7 → ≥ 5 → round up → 100
3. 31 → ones digit is 1 → < 5 → round down → 30
4. 35 → ones digit is 5 → ≥ 5 → round up → 40
5. 77 → ones digit is 7 → ≥ 5 → round up → 80
6. 49 → same as #1 → 50
7. 90 → already a multiple of 10 → 90
8. 70 → already a multiple of 10 → 70
9. 30 → already a multiple of 10 → 30
10. 41 → ones digit is 1 → < 5 → round down → 40
11. 174 → ones digit is 4 → < 5 → round down → 170
12. 900 → already a multiple of 10 → 900
13. 304 → ones digit is 4 → < 5 → round down → 300
14. 117 → ones digit is 7 → ≥ 5 → round up → 120
15. 439 → ones digit is 9 → ≥ 5 → round up → 440
16. 119 → ones digit is 9 → ≥ 5 → round up → 120
17. 883 → ones digit is 3 → < 5 → round down → 880
18. 399 → ones digit is 9 → ≥ 5 → round up → 400
19. 776 → ones digit is 6 → ≥ 5 → round up → 780
20. 321 → ones digit is 1 → < 5 → round down → 320
21. 4937 → ones digit is 7 → ≥ 5 → round up → 4940
22. 7434 → ones digit is 4 → < 5 → round down → 7430
23. 9075 → ones digit is 5 → ≥ 5 → round up → 9080
24. 7993 → ones digit is 3 → < 5 → round down → 7990
25. 4763 → ones digit is 3 → < 5 → round down → 4760
26. 2140 → already a multiple of 10 → 2140
27. 8385 → ones digit is 5 → ≥ 5 → round up → 8390
28. 4105 → ones digit is 5 → ≥ 5 → round up → 4110
29. 2110 → already a multiple of 10 → 2110
30. 6210 → already a multiple of 10 → 6210
