Let's solve the rounding problems step by step. We are asked to
round each number to the nearest hundred.
🔹 Rule for Rounding to the Nearest Hundred:
- 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 tens and ones digits with zeros.
