To understand the solution for this problem, let's go through each step carefully, focusing on the chosen numbers: 4, 8, 11, and 12.
Given:
```
Encircle 4, 8, 11, and 12
1. 1572 - (4) 811 (12)
2. 2.88 - 481112
3. 160 - 4 8 11 12
4. 642 - 4 8 1112
5. 2400 - 48 11 12
```
### Step-by-Step Analysis:
1. Interpreting the Problem:
- The instructions suggest encircling the numbers 4, 8, 11, and 12 in the given sequences.
2. Considering Each Line of Input:
- Line 1: `1572 - (4) 811 (12)`
- Here, 4 and 12 are in parentheses, indicating that we should notice these numbers.
- Line 2: `2.88 - 481112`
- There are no clear parentheses or separations here, but based on the instruction, we can look for 4, 8, 11, and 12 within this sequence.
- Line 3: `160 - 4 8 11 12`
- Numbers 4, 8, 11, and 12 are already clearly separated, making it easy to identify them.
- Line 4: `642 - 4 8 1112`
- Similarly, 4, 8, 11, and 12 are separated, with `11` and `12` potentially combined as 1112.
- Line 5: `2400 - 48 11 12`
- In this case, we see `48` which includes both `4` and `8`, followed by 11 and 12.
### Final Consolidation:
- We need to identify the numbers 4, 8, 11, and 12 from the provided sequences. The problem emphasizes focusing on these numbers specifically.
### Conclusion:
- By just focusing on the numbers 4, 8, 11, and 12 within each line, we directly list them out as required.
### Encircled Numbers:
- The required numbers to encircle based on the problem are: 4, 8, 11, and 12.
Thus, the final encircled numbers are:
- 4
- 8
- 11
- 12
This completes the solution.
