Skill: Round numbers to the nearest 1,000

To round a whole number to the nearest $1{,}000$, find the two consecutive multiples of $1{,}000$ that the number lies between.

• If the hundreds digit is $0,1,2,3,$ or $4$, round down.
• If the hundreds digit is $5,6,7,8,$ or $9$, round up.

Example: Round $6{,}742$ to the nearest $1{,}000$.

1. Find the thousands the number is between:

$$6{,}000 < 6{,}742 < 7{,}000$$

2. Look at the hundreds digit in $6{,}742$. The hundreds digit is $7$.

3. Since $7$ is $5$ or more, round up to the next thousand.

$$6{,}742 \approx 7{,}000$$

So, $6{,}742$ rounded to the nearest $1{,}000$ is $7{,}000$.
