Question

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

$49730\to 49700$

Answer 1

The following rounding off $49730\to 49700$ is incorrect as the given number's highest place value is ten thousand so we need to round off it to nearest ten thousand by checking its thousand's place digit.

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

Here thousand's digit is $9>5$.

So, $49730\to 49700$ is incorrect and the correct round off is $49730\to 50,000$.
