Question

Check if the following rounding off is Correct or not .Correct if it is wrong.

$149\to 100$

Answer 1

The following rounding off $149\to 100$ is correct as the given number's highest place value is hundred.So we will round off them to nearest hundred by checking their tens place digit.

For rounding off to nearest hundreds,we first check the digit at ten's place.If the digit at ten's place is less than $5$ then we replace its ten's and one's place by zero but if the digit at ten's place is$\ge 5$ then we add $1$ to hundred's place digit and then replace ten's place and one's place by zero.

Here ten's digits is $4<5$

So, $149\to 100$ is correct.
