Convert 12-hour clock times to 24-hour format and vice versa with this educational worksheet.

Problem: Converting 12-hour clock times to 24-hour clock times and vice versa, as well as reading analogue clocks.

#### Part 1: Convert these am and pm times into the 24-hour clock

The rules for converting 12-hour clock times to 24-hour clock times are:
- For am times: If the time is between 1:00 am and 12:59 am, keep the hour as it is (except for 12:00 am, which becomes 00:00).
- For pm times: Add 12 to the hour (except for 12:00 pm, which remains 12:00).

Let's solve each one:

1. 1:24 pm
- Add 12 to the hour: \(1 + 12 = 13\)
- The time is 13:24.

2. 2:56 am
- Keep the hour as it is:
- The time is 02:56.

3. 7:45 pm
- Add 12 to the hour: \(7 + 12 = 19\)
- The time is 19:45.

4. 5:16 am
- Keep the hour as it is:
- The time is 05:16.

5. 3:56 pm
- Add 12 to the hour: \(3 + 12 = 15\)
- The time is 15:56.

6. 12:25 pm
- 12:00 pm remains 12:00 in the 24-hour format:
- The time is 12:25.

7. 11:27 pm
- Add 12 to the hour: \(11 + 12 = 23\)
- The time is 23:27.

8. 8:13 pm
- Add 12 to the hour: \(8 + 12 = 20\)
- The time is 20:13.

9. 12:42 am
- 12:00 am becomes 00:00 in the 24-hour format:
- The time is 00:42.

#### Answers for Part 1:
1. 13:24
2. 02:56
3. 19:45
4. 05:16
5. 15:56
6. 12:25
7. 23:27
8. 20:13
9. 00:42

#### Part 2: Convert these 24-hour clock times to am and pm times

The rules for converting 24-hour clock times to 12-hour clock times are:
- For hours 00 to 11: These are am times. If the hour is 00, convert it to 12:00 am.
- For hours 12 to 23: Subtract 12 from the hour to get the corresponding pm time. If the hour is 12, it remains 12:00 pm.

Let's solve each one:

1. 13:41
- Subtract 12 from the hour: \(13 - 12 = 1\)
- The time is 1:41 pm.

2. 17:50
- Subtract 12 from the hour: \(17 - 12 = 5\)
- The time is 5:50 pm.

3. 04:32
- The hour is between 00 and 11, so it is an am time:
- The time is 4:32 am.

4. 12:36
- 12:00 remains 12:00 in the 12-hour format:
- The time is 12:36 pm.

5. 23:25
- Subtract 12 from the hour: \(23 - 12 = 11\)
- The time is 11:25 pm.

6. 08:53
- The hour is between 00 and 11, so it is an am time:
- The time is 8:53 am.

7. 00:51
- 00:00 becomes 12:00 am:
- The time is 12:51 am.

8. 19:08
- Subtract 12 from the hour: \(19 - 12 = 7\)
- The time is 7:08 pm.

9. 15:39
- Subtract 12 from the hour: \(15 - 12 = 3\)
- The time is 3:39 pm.

#### Answers for Part 2:
1. 1:41 pm
2. 5:50 pm
3. 4:32 am
4. 12:36 pm
5. 11:25 pm
6. 8:53 am
7. 12:51 am
8. 7:08 pm
9. 3:39 pm

#### Part 3: Write the correct 24-hour clock time with each analogue clock

To read the time on an analogue clock:
- The hour hand indicates the hour.
- The minute hand indicates the minutes past the hour.

Let's solve each one:

1. First Clock:
- Hour hand is between 7 and 8, closer to 7.
- Minute hand is at 8, which is 40 minutes past the hour.
- The time is 07:40.

2. Second Clock:
- Hour hand is between 10 and 11, closer to 10.
- Minute hand is at 9, which is 45 minutes past the hour.
- The time is 10:45.

3. Third Clock:
- Hour hand is between 5 and 6, closer to 5.
- Minute hand is at 3, which is 15 minutes past the hour.
- The time is 05:15.

4. Fourth Clock:
- Hour hand is between 1 and 2, closer to 1.
- Minute hand is at 12, which is 0 minutes past the hour.
- The time is 01:00.

5. Fifth Clock:
- Hour hand is between 10 and 11, closer to 10.
- Minute hand is at 10, which is 50 minutes past the hour.
- The time is 10:50.

6. Sixth Clock:
- Hour hand is between 4 and 5, closer to 4.
- Minute hand is at 8, which is 40 minutes past the hour.
- The time is 04:40.

7. Seventh Clock:
- Hour hand is between 8 and 9, closer to 8.
- Minute hand is at 6, which is 30 minutes past the hour.
- The time is 08:30.

8. Eighth Clock:
- Hour hand is between 7 and 8, closer to 7.
- Minute hand is at 6, which is 30 minutes past the hour.
- The time is 07:30.
