Let's solve the problem step by step.
We are asked to
round off each number to the nearest thousand. To do this, we follow these rules:
🔹 Rounding Rules (to the nearest thousand):
- Look at the
hundreds digit (the third digit from the right).
- If it is
5 or more, round
up.
- If it is
less than 5, round
down.
- Replace the last three digits with zeros.
