Let's solve the rounding worksheet step by step. The task is to
round each number to the nearest 100.
🔍 Rounding Rule:
To round a number to the nearest 100:
- Look at the
tens digit (the second digit from the right).
- If it is
5 or more, round
up.
- If it is
less than 5, round
down.
- Replace the last two digits with zeros.
