Steps to Solve
- Identify the relevant digits
Look at the number provided. Find the digit in the hundred thousand place. For example, in the number 2,347,829, the hundred thousand digit is 2.

Look at the digit immediately to the right of the hundred thousand digit to determine whether to round up or down. In our example, the digit in the ten thousand place is 3.
- Decide to round up or down
If the digit in the ten thousand place is 5 or greater, round up the hundred thousand digit by 1. If it is less than 5, keep the hundred thousand digit the same. In our example, since 3 is less than 5, we won’t round up.
- Form the rounded number
Replace all digits to the right of the hundred thousand digit with zeros. Therefore, the number becomes 2,300,000 for our example.
The rounded number is $2,300,000$.
