Show Answer Key & Explanations Step-by-step solution for: Convert between 12-Hour and 24-Hour Clocks Worksheets
The image you uploaded appears to be a worksheet titled "24 Hour Clock," which involves converting times shown on analog clocks into both 12-hour and 24-hour formats. Below is a step-by-step explanation of how to solve such problems, along with an example.

---

Understanding the Problem


1. Analog Clocks: Each clock in the worksheet shows a specific time.
2. Conversion Tasks:
- Convert the time shown on the clock into the 12-hour format (e.g., 3:00 PM).
- Convert the time shown on the clock into the 24-hour format (e.g., 15:00).

Key Concepts


- 12-Hour Format: Uses AM/PM notation. Times range from 1:00 AM to 12:00 PM (noon) and then from 1:00 PM to 12:00 AM (midnight).
- 24-Hour Format: Uses a continuous count from 00:00 (midnight) to 23:59.
- Hours from 1:00 PM to 11:59 PM are represented as 13:00 to 23:59.
- Midnight is 00:00, and noon is 12:00.

Steps to Solve


1. Identify the Time on the Clock:
- Look at the hour and minute hands to determine the exact time.
- For example, if the hour hand is on 3 and the minute hand is on 12, the time is 3:00.

2. Convert to 12-Hour Format:
- If the time is before noon (midnight to 11:59), use AM.
- If the time is after noon (12:00 to 11:59 PM), use PM.
- Example: 3:00 becomes 3:00 AM or 3:00 PM depending on the context.

3. Convert to 24-Hour Format:
- For times before noon (1:00 AM to 11:59 AM), the 24-hour format is the same as the 12-hour format.
- For times after noon (1:00 PM to 11:59 PM), add 12 to the hour.
- Example: 3:00 PM becomes 15:00.

Example Solution


Let's take one of the clocks from the worksheet as an example:

#### Clock Image: The hour hand is on 7, and the minute hand is on 12.
- Time on the Clock: 7:00

#### Step 1: Identify the Time
- The time shown is 7:00.

#### Step 2: Convert to 12-Hour Format
- Since the problem does not specify AM or PM, we assume it could be either.
- If it's in the morning: 7:00 AM
- If it's in the evening: 7:00 PM

#### Step 3: Convert to 24-Hour Format
- For 7:00 AM: The 24-hour format is 07:00.
- For 7:00 PM: Add 12 to the hour (7 + 12 = 19), so the 24-hour format is 19:00.

#### Final Answer for This Clock
- 12-Hour Format: 7:00 AM or 7:00 PM
- 24-Hour Format: 07:00 or 19:00

General Approach for All Clocks


- Repeat the above steps for each clock in the worksheet.
- Pay attention to whether the time is in the morning (AM) or evening (PM) when converting to the 12-hour format.
- Use the rules for adding 12 to convert PM times to the 24-hour format.

Final Answer


If you provide the specific times shown on the clocks in the worksheet, I can give you the exact conversions for each one. Otherwise, the general method described above should help you solve the entire worksheet.

Boxed Final Answer (General Method):
$$
\boxed{\text{Follow the steps above for each clock to convert to 12-hour and 24-hour formats.}}
$$
