How do you round up or down when the last digit of significant digit is 5?
When the last digit of a significant digit is 5 and we need to round it, we follow a rule called "round half up". This means that we round the digit up to the nearest number if the digit before it is odd, and round down if it's even. For example, 2.5 would round up to 3, while 3.5 would also round up to 4.

There are certain rules to follow when rounding a decimal number. Put simply, if the last digit is less than 5, round the previous digit down.

Round to the nearest ten 627?
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!
