## 📌 Part 1: Round to the Nearest 10

We look at the ones digit (the digit in the units place).
- If it’s 5 or greater, round up.
- If it’s 4 or less, round down.

Let’s go one by one:

1. 45 → ones digit is 5 → round up → 50
2. 67 → ones digit is 7 → round up → 70
3. 82 → ones digit is 2 → round down → 80
4. 39 → ones digit is 9 → round up → 40
5. 74 → ones digit is 4 → round down → 70
6. 12 → ones digit is 2 → round down → 10
7. 93 → ones digit is 3 → round down → 90
8. 44 → ones digit is 4 → round down → 40
9. 25 → ones digit is 5 → round up → 30
10. 65 → ones digit is 5 → round up → 70
