To round 352,109 to the nearest hundred thousand, you need to consider the digit in the hundred thousand place (the leftmost place value).

Here's how you can do it:
1. Look at the digit in the hundred thousand place, which is 3 in this case.
2. Look at the digit immediately to its right, which is 5.
3. If the digit to the right is 5 or greater, you round up. If it's less than 5, you round down.
4. Since 5 is greater than 5, you need to round up.
5. Increase the digit in the hundred thousand place by 1, making it 4.
6. Change all the digits to the right of the hundred thousand place to zero.
7. The rounded number to the nearest hundred thousand is 400,000.

Therefore, 352,109 rounded to the nearest hundred thousand is 400,000.
