In the image, two problems require rounding each number to the nearest hundred, estimating the sum, and solving the actual addition problem. Here’s how they can be solved:

### Problem 4:
**Original problem:**  
\( 147 + 364 \)

**Estimation by rounding to the nearest hundred:**  
- 147 rounds to 100  
- 364 rounds to 400  

**Estimated sum:**  
\( 100 + 400 = 500 \)

**Actual sum:**  
\( 147 + 364 = 511 \)

---

### Problem 5:
**Original problem:**  
\( 704 + 195 \)

**Estimation by rounding to the nearest hundred:**  
- 704 rounds to 700  
- 195 rounds to 200  

**Estimated sum:**  
\( 700 + 200 = 900 \)

**Actual sum:**  
\( 704 + 195 = 899 \)

Here are 5 related questions to extend your learning:
1. How do you round numbers to the nearest ten?
2. What would the sum be if you rounded each number in Problem 4 to the nearest ten instead of the nearest hundred?
3. Why is estimation important in solving math problems?
4. What is the difference between an exact sum and an estimated sum?
5. Can you think of a real-life scenario where estimation might be more useful than an exact answer?

**Tip:** Estimation helps check whether your final answer is reasonable and close to what you expected, especially for quick mental math!

Round each number to the nearest hundred to estimate. Solve the given addition problems: 147 + 364 and 704 + 195.
