Question

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

$2546\to 2500$

Answer 1

The following rounding off $2546\to 2500$ is incorrect as the given number's highest place value is thousand so we need to round off it to nearest thousand by checking its hundred's place digit.

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

Here hundred's digits is $5=5$.

So, $2546\to 2500$ is incorrect and the correct round off is $2546\to 2600$.
