4. 0.77 → hundredths digit is 7 → round up → 0.8
5. 3.95 → hundredths digit is 5 → round up → 4.0
6. 2.81 → hundredths digit is 1 → round down → 2.8
7. 3.15 → hundredths digit is 5 → round up → 3.2
8. 0.04 → hundredths digit is 4 → round down → 0.0
9. 0.44 → hundredths digit is 4 → round down → 0.4
10. 1.23 → hundredths digit is 3 → round down → 1.2
11. 1.77 → hundredths digit is 7 → round up → 1.8
12. 3.62 → hundredths digit is 2 → round down → 3.6

🔍 Explanation:

- The tenth is the first digit after the decimal point.
- To round, check the second digit after the decimal (hundredths):
- If ≥ 5 → increase the tenths digit by 1.
- If < 5 → keep the tenths digit the same.
- Special case: when rounding up from 9 (e.g., 3.95 → 4.0), the whole number increases.

✔ All answers follow this rule.
