Round 7-digit numbers to the nearest 10,000 - math practice worksheet.

To solve the problem of rounding 7-digit numbers to the nearest 10,000, we need to follow these steps:

Steps for Rounding to the Nearest 10,000:

1. Identify the digit in the thousands place: This is the fourth digit from the right.
2. Look at the digit in the hundreds place: This is the third digit from the right.
- If the hundreds digit is 5 or greater, round up the thousands digit by 1.
- If the hundreds digit is less than 5, keep the thousands digit as it is.
3. Replace all digits to the right of the thousands place with zeros.

Let's apply this step-by-step to each number:
