We have learnt in our previous class how to round off a number to a certain place.
To round off a number, we look at the digit to the
right of the place to which you are rounding. Remember

If the digit is 5 or greater, round up. A number can be rounded off to
any place according to the situation.
If the digit is less than 5, round down. But the estimated answer should be
close to the actual answer.
