Rounding Numbers worksheet with exercises for rounding to the nearest 10 and 100.

To round numbers to the nearest 10, look at the digit in the ones place (the last digit):
- If it is 5 or more, round up to the next ten.
- If it is 4 or less, round down to the current ten.

Let’s go step by step for each number:

First section: Round to nearest 10

1. 26 → ones digit is 6 → 6 ≥ 5 → round up → 30
2. 37 → ones digit is 7 → 7 ≥ 5 → round up → 40
3. 73 → ones digit is 3 → 3 < 5 → round down → 70
4. 65 → ones digit is 5 → 5 ≥ 5 → round up → 70
5. 49 → ones digit is 9 → 9 ≥ 5 → round up → 50
6. 33 → ones digit is 3 → 3 < 5 → round down → 30
7. 86 → ones digit is 6 → 6 ≥ 5 → round up → 90
8. 51 → ones digit is 1 → 1 < 5 → round down → 50
9. 12 → ones digit is 2 → 2 < 5 → round down → 10
10. 92 → ones digit is 2 → 2 < 5 → round down → 90

Second section: Round to nearest 100

Now we look at the tens digit (second from right) to decide whether to round up or down to the nearest hundred.

Rule:
- If tens digit is 5 or more, round up.
- If tens digit is 4 or less, round down.

1. 320 → tens digit is 2 → 2 < 5 → round down → 300
2. 280 → tens digit is 8 → 8 ≥ 5 → round up → 300
3. 890 → tens digit is 9 → 9 ≥ 5 → round up → 900
4. 110 → tens digit is 1 → 1 < 5 → round down → 100
5. 460 → tens digit is 6 → 6 ≥ 5 → round up → 500
6. 730 → tens digit is 3 → 3 < 5 → round down → 700
7. 610 → tens digit is 1 → 1 < 5 → round down → 600
8. 190 → tens digit is 9 → 9 ≥ 5 → round up → 200
9. 550 → tens digit is 5 → 5 ≥ 5 → round up → 600
10. 940 → tens digit is 4 → 4 < 5 → round down → 900
