Let’s go step by step to convert each 12-hour time to 24-hour time.

Rule:
- For AM times:
- If it’s 12:00am → that’s 00:00 in 24-hour time.
- Otherwise, just keep the same numbers (no change).
Example: 8:55am = 08:55

- For PM times:
- If it’s 12:00pm → that’s 12:00 in 24-hour time.
- Otherwise, add 12 to the hour.
Example: 3:35pm → 3 + 12 = 15 → so 15:35

Now let’s solve each one:

---

1. 3:35pm → PM, not 12 → 3 + 12 = 15 → 15:35

2. 8:55am → AM, not 12 → stays 08:55

3. 9:15pm → PM, not 12 → 9 + 12 = 21 → 21:15

4. 6:40am → AM → 06:40

5. 5:00pm → PM → 5 + 12 = 17 → 17:00

6. 4:45am → AM → 04:45

7. 7:30pm → PM → 7 + 12 = 19 → 19:30

8. 2:35am → AM → 02:35

9. 4:15pm → PM → 4 + 12 = 16 → 16:15

10. 5:30am → AM → 05:30

11. 6:45pm → PM → 6 + 12 = 18 → 18:45

12. 10:55am → AM → 10:55

13. 10:00pm → PM → 10 + 12 = 22 → 22:00

14. 11:15am → AM → 11:15

15. 3:50pm → PM → 3 + 12 = 15 → 15:50

16. 9:20am → AM → 09:20

17. 7:35pm → PM → 7 + 12 = 19 → 19:35

18. 2:50am → AM → 02:50

19. 10:25pm → PM → 10 + 12 = 22 → 22:25

20. 11:30am → AM → 11:30
