Rounding Decimals worksheet for practicing rounding decimal numbers to the nearest whole number.

Let's solve the problem step by step.

Task:

Round each decimal number to the nearest whole number.

---

Rule for Rounding to the Nearest Whole Number:

- Look at the tenths place (the first digit after the decimal point).
- If it is 5 or greater, round up.
- If it is less than 5, round down.

Now, let’s go through each number:

1. 2.94 → Tenths digit is 9 → Round up → 3
2. 34.33 → Tenths digit is 3 → Round down → 34
3. 44.9 → Tenths digit is 9 → Round up → 45
4. 17.723 → Tenths digit is 7 → Round up → 18
5. 59.04 → Tenths digit is 0 → Round down → 59
6. 119.6 → Tenths digit is 6 → Round up → 120
7. 39.672 → Tenths digit is 6 → Round up → 40
8. 88.667 → Tenths digit is 6 → Round up → 89
9. 68.841 → Tenths digit is 8 → Round up → 69
10. 0.993 → Tenths digit is 9 → Round up → 1
11. 1.137 → Tenths digit is 1 → Round down → 1
12. 80.82 → Tenths digit is 8 → Round up → 81
13. 39.762 → Tenths digit is 7 → Round up → 40
14. 72.93 → Tenths digit is 9 → Round up → 73
15. 8.72 → Tenths digit is 7 → Round up → 9
16. 6.6794 → Tenths digit is 6 → Round up → 7
17. 3.898 → Tenths digit is 8 → Round up → 4
18. 2.93 → Tenths digit is 9 → Round up → 3
