To round a number to the nearest ten thousand, you look at the thousands digit (which is the digit in the fourth place to the left of the decimal point). If that digit is 5 or greater, you round up. If it is 4 or less, you round down.
In the number 354,567.929:
- The digit in the ten thousands place is 5 (it's the second digit from the left).
- The digit in the thousands place is 4.
Since the thousands place is 4, which is less than 5, you do not round up the ten thousands place.
Therefore, the number rounded to the nearest ten thousand is 350,000.
