Rounding to nearest 10,000 worksheet - Free Printable

Problem Description:

The task is to round the given numbers to the nearest ten thousand. This involves identifying the digit in the ten-thousands place and determining whether to round up or down based on the digit in the thousands place.

Steps to Solve:

1. Identify the Ten-Thousands Place: The ten-thousands place is the fifth digit from the right in a number.
2. Look at the Thousands Place: The thousands place is the fourth digit from the right. If this digit is 5 or greater, round up; if it is less than 5, round down.
3. Round the Number:
- If rounding up, increase the digit in the ten-thousands place by 1 and set all digits to the right to 0.
- If rounding down, keep the digit in the ten-thousands place as it is and set all digits to the right to 0.
