To round 627 to the nearest ten, we look at the digit in the ones place, which is 7. If the digit in the ones place is 5 or greater, we round up. If the digit in the ones place is less than 5, we round down. Since 7 is greater than 5, we round 627 up to 630.
Here is a table showing how to round different digits in the ones place:
| Digit in the ones place | Rounding direction |
|---|---|---|
| 0, 1, 2, 3, or 4 | Round down |
| 5, 6, 7, 8, or 9 | Round up |
I hope this helps!
