Question

BlackTom AI · Accepted Answer

A percentage of 12% represents the proportion of surveyed Australian teenagers who often continue to use social media after 1am.

1. Relevant knowledge points and concepts
- Percentage interpretation: Percent means “per hundred.” Saying “12% of teenagers” means 12 out of every 100, or the fraction 12/100 = 0.12 of the population/sample.
- Survey/report reading: The figure given (12%) is the reported approximate proportion from the study or data source and is already rounded to an appropriate precision.

2. Step-by-step reasoning process
- Identify the reported statistic in the question text or figure: it shows “Approximately 12%.”
- Interpret that statistic as the proportion of the population (Australian teenagers) who often continue to use social media after 1am.
- Confirm that no further calculation or conversion is required because the answer is requested as a percentage and is already provided.

3. Calculations and intermediate steps (illustrative)
- Percent → fraction: 12% = 12/100 = 0.12.
- Example conversions to concrete counts (equivalent representations):
  - If the sample were 100 teenagers, 0.12 × 100 = 12 teenagers.
  - If the sample were 500 teenagers, 0.12 × 500 = 60 teenagers.
  - If the sample were 1,000 teenagers, 0.12 × 1,000 = 120 teenagers.
These examples show how the 12% value translates to counts for different sample sizes.

4. Why the correct answer is correct
- The question asks for the approximate percentage and the provided data point is 12%. That directly satisfies the prompt: 12% is the approximate share of Australian teenagers who often continue to use social media after 1am.

5. Why other options are incorrect (brief)
- No alternative choices are given in this short-answer item. If other percentages (for example, 8%, 20%, etc.) were offered, they would be incorrect because they do not match the reported statistic of 12% shown in the source.

6. Conclusion
- The correct and confirmed answer is 12%, matching the provided data point and the authoritative answer.
