Question

Round off $40,386$ to the nearest thousand.

Answer 1

Estimation to nearest $1000$:

To round off to nearest $1000$, look at the digit in the hundreds place. If it is $5$ or more, then round up, i.e. replace the digits at ones, tens and hundreds place by $0$ and add $1$ to the digit at the thousands place. If it is less than $5$, then round down, i.e. replace the digits at ones, tens and hundreds place by zero and leave the digit at thousands place unchanged.

Here, the digit at hundreds place is $3<5$.

So, round down the given number.

Thus, $40,386$ is rounded off to $40,000$.
