Rounding Numbers Worksheets: Round To The Nearest 100 | MomJunction - Free Printable

Let's solve the problem step by step.

We are asked to round each number to the nearest 100.
To round a number to the nearest 100:

- If the tens digit is 5 or more, round up.
- If the tens digit is less than 5, round down.
