The question asks to select multiplication expressions that have an estimated product of about 240,000. Let’s estimate each pair of numbers by rounding to the nearest hundred and then calculate the approximate product:

1. **322 × 814**  
   - Round 322 to **300**  
   - Round 814 to **800**  
   - Estimate: \(300 \times 800 = 240,000\)

2. **291 × 782**  
   - Round 291 to **300**  
   - Round 782 to **800**  
   - Estimate: \(300 \times 800 = 240,000\)

3. **396 × 584**  
   - Round 396 to **400**  
   - Round 584 to **600**  
   - Estimate: \(400 \times 600 = 240,000\)

4. **367 × 478**  
   - Round 367 to **400**  
   - Round 478 to **500**  
   - Estimate: \(400 \times 500 = 200,000\) (This is less than 240,000)

5. **388 × 892**  
   - Round 388 to **400**  
   - Round 892 to **900**  
   - Estimate: \(400 \times 900 = 360,000\) (This is more than 240,000)

### Conclusion:
The following multiplication expressions are close to 240,000:
- **322 × 814**
- **291 × 782**
- **396 × 584**

Here are 5 follow-up questions based on this:
1. Why is it important to round numbers when estimating products?
2. What would the exact product of 322 × 814 be?
3. Could other rounding methods give different estimates?
4. How can we refine estimates further if needed?
5. What are other ways to quickly check if an estimate is reasonable?

**Tip:** When estimating, rounding to the nearest hundred or thousand helps simplify complex calculations!
