24 Hour Clock - Write the Time (digital & analogue) | Teaching ... - Free Printable

Problem Overview:

The task involves converting times given in the 12-hour format (e.g., "2:15 pm") into the 24-hour format and then expressing them in words. The first example is already provided as a reference:

- 12-hour time: 2:15 pm
- 24-hour time: 14:15
- Analogue time in words: Quarter past two

We need to follow this pattern for the remaining times.

Solution:

#### Step 1: Understand the Conversion Rules
1. From 12-hour to 24-hour format:
- For times in the PM period (12:00 PM to 11:59 PM), add 12 to the hour part of the time.
- For times in the AM period (12:00 AM to 11:59 AM), keep the hour as is (except for 12:00 AM, which becomes 00:00).

2. Expressing Time in Words:
- Use terms like "quarter past," "half past," "quarter to," etc., to describe the minutes.
- For exact hours, simply state the hour (e.g., "two o'clock").

#### Step 2: Solve Each Time

##### Time 2: 5:25 pm
- 12-hour time: 5:25 pm
- 24-hour time: Since it is in the PM period, add 12 to the hour:
\[
5 + 12 = 17
\]
So, the 24-hour time is 17:25.
- Analogue time in words:
- 25 minutes past the hour is expressed as "twenty-five past five."
- Therefore, the time in words is "Twenty-five past five".

##### Time 3: 3:35 pm
- 12-hour time: 3:35 pm
- 24-hour time: Since it is in the PM period, add 12 to the hour:
\[
3 + 12 = 15
\]
So, the 24-hour time is 15:35.
- Analogue time in words:
- 35 minutes past the hour is expressed as "thirty-five past three."
- Therefore, the time in words is "Thirty-five past three".

##### Time 4: 4:50 pm
- 12-hour time: 4:50 pm
- 24-hour time: Since it is in the PM period, add 12 to the hour:
\[
4 + 12 = 16
\]
So, the 24-hour time is 16:50.
- Analogue time in words:
- 50 minutes past the hour is expressed as "ten to five" (since 60 - 50 = 10).
- Therefore, the time in words is "Ten to five".

##### Time 5: 6:25 pm
- 12-hour time: 6:25 pm
- 24-hour time: Since it is in the PM period, add 12 to the hour:
\[
6 + 12 = 18
\]
So, the 24-hour time is 18:25.
- Analogue time in words:
- 25 minutes past the hour is expressed as "twenty-five past six."
- Therefore, the time in words is "Twenty-five past six".

#### Step 3: Organize the Answers

| S.No | 12-hour Time | Digital Time | Analogue Time |
|------|--------------|--------------|------------------------|
| 1 | 2:15 pm | 14:15 | Quarter past two |
| 2 | 5:25 pm | 17:25 | Twenty-five past five |
| 3 | 3:35 pm | 15:35 | Thirty-five past three |
| 4 | 4:50 pm | 16:50 | Ten to five |
| 5 | 6:25 pm | 18:25 | Twenty-five past six |

Final Answer:

\[
\boxed{
\begin{array}{|c|c|c|c|}
\hline
\text{S.No} & \text{12-hour Time} & \text{Digital Time} & \text{Analogue Time} \\
\hline
1 & 2:15 \text{ pm} & 14:15 & \text{Quarter past two} \\
2 & 5:25 \text{ pm} & 17:25 & \text{Twenty-five past five} \\
3 & 3:35 \text{ pm} & 15:35 & \text{Thirty-five past three} \\
4 & 4:50 \text{ pm} & 16:50 & \text{Ten to five} \\
5 & 6:25 \text{ pm} & 18:25 & \text{Twenty-five past six} \\
\hline
\end{array}
}
