Round to the nearest 10 and 100 worksheet - Free Printable

Problem Description:

The task is to round the given numbers to the nearest 10 and the nearest 100. The worksheet provides two columns for each number: one for rounding to the nearest 10 and another for rounding to the nearest 100.

Solution Approach:

1. Rounding to the Nearest 10:
- Look at the digit in the ones place.
- If the ones digit is 5 or greater, round up.
- If the ones digit is less than 5, round down.

2. Rounding to the Nearest 100:
- Look at the digit in the tens place.
- If the tens digit is 5 or greater, round up.
- If the tens digit is less than 5, round down.
