The image contains two sections of problems. Here is a transcription and breakdown:

### Section 1: Arithmetic Operations
1. **9,684,250**  
   - \( \div 4 = 2,421,062.5 \)
   - \( \times 31 = 299,346,937.5 \)

2. **1,280,945**  
   - \( \times 73 = 93,505,985 \)

3. **1,487,500**  
   - (No operation or result specified)

### Section 2: Word Problems
1. **Word Problem:**
   - "Study the number 3870 and answer the question below."
   - "Will the number 3870 be even when 1,000 is subtracted from the number?"
     - Subtracting 1,000 from 3870 gives 2870. Since the last digit is 0, it is even.

   - "What digit gets the previous value?"
     - After subtracting 1,000, the previous value's last digit changes from 7 to 8.

   - "What is the value of?"
     - The question seems incomplete or unclear. However, it likely refers to either the new number or the difference.

Would you like more detailed explanations for any of these problems or answers? 

### Follow-Up Questions:
1. Can you explain why subtracting 1,000 from an even number still results in an even number?
2. What is the general rule for determining if a number is even or odd?
3. How can you check the accuracy of the arithmetic operations using different methods?
4. What might be the value or significance of the "previous value" mentioned in the word problem?
5. Why might the multiplication result in Section 1 be important for understanding large number operations?

### Tip:
When subtracting large numbers, always ensure each digit is handled carefully, especially with borrowing across zeros.
