Question

Round off the following number to the nearest ten thousands: $77,723$

Answer 1

To round off to the nearest ten thousands

Step 1: Check the thousands place digit of the given number.

Here, the thousands place digit of $77,723$ is $7$.

Step 2: If thousands place digit $<$ $5$, replace the thousands, hundreds, tens and ones place digits by $0$ and keep other digits same. If thousands place digit is $⩾$$5$, replace the thousands, hundreds, tens and ones place digits by $0$ and increase the ten thousands digit by $1$ keeping other digits same.

Since, $7>5$, the thousands, hundreds, tens and ones place digits are replaced by $0$ and ten thousands place digit will be increased $1$.

So, $77,723$ rounded off to the nearest ten thousands is $80,000$.

Hence, $77,723$ rounded off to the nearest ten thousands is $80,000$.
