Let’s solve this step by step.

We are converting between 12-hour clock (with a.m. and p.m.) and 24-hour clock (military time, no a.m./p.m.).

Part 1: Convert 12-hour to 24-hour

Rules:
- For a.m. times:
→ If it’s 12:00 a.m., that becomes 00:00 in 24-hour.
→ Otherwise, just keep the same numbers (but write with 4 digits if needed — e.g., 8:30 a.m. = 08:30).

- For p.m. times:
→ If it’s 12:00 p.m., that stays 12:00.
→ Otherwise, add 12 to the hour (e.g., 2:55 p.m. = 2 + 12 = 14 → 14:55).

Now let’s go one by one:

1. 2:55 p.m. → 2 + 12 = 14 → 14:55
2. 8:30 a.m. → already a.m., not 12 → 08:30
3. 9:12 p.m. → 9 + 12 = 21 → 21:12
4. 12:15 a.m. → special case → 00:15
5. 7:40 a.m. → already a.m. → 07:40
6. 6:25 p.m. → 6 + 12 = 18 → 18:25
7. 4:00 a.m. → already a.m. → 04:00
8. 11:50 p.m. → 11 + 12 = 23 → 23:50
9. 12:00 p.m. → special case → 12:00
10. 7:20 a.m. → already a.m. → 07:20
11. 2:15 p.m. → 2 + 12 = 14 → 14:15
12. 1:50 p.m. → 1 + 12 = 13 → 13:50

Part 2: Convert 24-hour to 12-hour

Rules:
- If hour is 00, change to 12 a.m.
- If hour is 12, keep as 12 p.m.
- If hour is 1–11, keep same number and add a.m.
- If hour is 13–23, subtract 12 and add p.m.

Let’s do each:

1. 18:10 → 18 - 12 = 6 → 6:10 p.m.
2. 08:45 → less than 12 → 8:45 a.m.
3. 11:00 → less than 12 → 11:00 a.m.
4. 17:26 → 17 - 12 = 5 → 5:26 p.m.
5. 23:35 → 23 - 12 = 11 → 11:35 p.m.
6. 03:30 → less than 12 → 3:30 a.m.
7. 00:00 → special → 12:00 a.m.
8. 06:10 → less than 12 → 6:10 a.m.
9. 19:25 → 19 - 12 = 7 → 7:25 p.m.
10. 13:55 → 13 - 12 = 1 → 1:55 p.m.
11. 4:22 → wait! This is written as “4:22” but in 24-hour format, it should be 04:22? But since it's listed under 24-hour column, we assume it’s 04:22 → so 4:22 a.m.
→ Actually, looking at the table, it says “4:22” under 24-hour Clock — that must be a typo or shorthand for 04:22. So yes → 4:22 a.m.
12. 19:40 → 19 - 12 = 7 → 7:40 p.m.

Wait — double-check #11: The table says “4:22” under 24-hour Clock. In proper 24-hour format, single-digit hours have leading zero, so 4:22 means 04:22 → which is 4:22 a.m. Correct.
