Question

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

$286\to 200$

Answer 1

The following rounding off $286\to 200$ is incorrect as the given number's highest place value is hundred so we need to round off it to nearest hundred by checking its ten's place digit.

For rounding off to nearest hundred ,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 $8>5$.

So, $286\to 200$ is incorrect and the correct round off is $286\to 300$.
