To solve this worksheet, we need to convert each 24-hour clock time into a 12-hour clock time. Here’s how it works:
- If the hour is less than or equal to 12, keep the same number and add “AM” if it’s before noon (before 12:00), or “PM” if it’s after noon (from 12:00 onward).
- If the hour is greater than 12, subtract 12 from the hour and add “PM”.
- Special case: 00:xx becomes 12:xx AM.
Let’s go one by one:
1) 15:00 → 15 - 12 = 3 → 3:00 PM
2) 00:30 → This is midnight → 12:30 AM
3) 19:45 → 19 - 12 = 7 → 7:45 PM
4) 02:10 → Less than 12 → 2:10 AM
5) 21:05 → 21 - 12 = 9 → 9:05 PM
6) 13:25 → 13 - 12 = 1 → 1:25 PM
7) 17:55 → 17 - 12 = 5 → 5:55 PM
8) 23:05 → 23 - 12 = 11 → 11:05 PM
9) 05:40 → Less than 12 → 5:40 AM
All conversions are verified. Now here are the answers in order:
Final Answer:
1) 3:00 PM
2) 12:30 AM
3) 7:45 PM
4) 2:10 AM
5) 9:05 PM
6) 1:25 PM
7) 5:55 PM
8) 11:05 PM
9) 5:40 AM
