Let’s work through each time and convert it to 24-hour clock format.
Remember:
- For AM times (before noon), just write the time as is — but make sure to use two digits for hours if needed (e.g., 1 am → 01:00).
- For PM times (after noon), add 12 to the hour — unless it’s 12 pm (midday), which stays 12:00.
- Midnight is 00:00, not 24:00 in 24-hour clock.
Now let’s go one by one:
1. 6:25 pm → 6 + 12 = 18 →
18:25 ✔ (already done)
2. Quarter past 2 (am) → 2:15 am →
02:15 ✔ (already done)
3. 8:55 pm → 8 + 12 = 20 →
20:55
4. Half past 1 (pm) → 1:30 pm → 1 + 12 = 13 →
13:30
5. 7:20 am → stays same →
07:20
6. Twenty past 4 (am) → 4:20 am →
04:20
7. 25 minutes to 10 (pm) → That means 9:35 pm → 9 + 12 = 21 →
21:35
8. 12 o’clock (midnight) → This is 00:00 →
00:00
9. 2:30 (pm) → 2 + 12 = 14 →
14:30
10. Ten past 11 (pm) → 11:10 pm → 11 + 12 = 23 →
23:10
11. 5 minutes past 5 (am) → 5:05 am →
05:05
12. Ten to 8 (pm) → That means 7:50 pm → 7 + 12 = 19 →
19:50
13. Six o’clock (pm) → 6:00 pm → 6 + 12 = 18 →
18:00
14. 3:55 (pm) → 3 + 12 = 15 →
15:55
15. Twenty five past 12 (am) → 12:25 am → stays 12:25? Wait — no! In 24-hour clock, 12 am is midnight → so 12:25 am is actually
00:25
Wait — let’s double-check that.
Actually, in 24-hour time:
- 12:00 am = 00:00
- So 12:25 am = 00:25 → yes, correct.
But sometimes people get confused — 12 pm is midday (12:00), 12 am is midnight (00:00). So 12:25 am is 25 minutes after midnight → 00:25.
So →
00:25
16. 1:20 (pm) → 1 + 12 = 13 →
13:20
Let me verify a few tricky ones again:
- #7: “25 minutes to 10 (pm)” → 10 pm minus 25 min = 9:35 pm → 9+12=21 → 21:35 ✔️
- #8: “12 o’clock (midnight)” → definitely 00:00 ✔️
- #15: “Twenty five past 12 (am)” → 12:25 am → since it’s am and 12, it’s 00:25 ✔️
All look good.
Final Answer:
3. 20:55
4. 13:30
5. 07:20
6. 04:20
7. 21:35
8. 00:00
9. 14:30
10. 23:10
11. 05:05
12. 19:50
13. 18:00
14. 15:55
15. 00:25
16. 13:20
