# What Are the Rules That Govern Rounding of Whole Numbers?

When rounding a whole number, it is important to identify first the digit being rounded with its place value, such as tens, or hundreds. Once the rounding digit is identified the rule is to look at the number that is to the right of the rounding digitto see if it is less than or greater than 5. If this number is 5 or greater, the rounding digit increases by 1and the digits to the right of it become zeros.

Continue ReadingIf this number is less than 5, then the rounding digit stays the same and numbers to the right of it becomezeros. An example of using this rule is to round the whole number 547 to the nearest ten. Identifying the rounding digit in thetens place valuegives the number 4. The number that is to the right of 4 is 7, which is greater than 5. Following the rule, the rounding digit 4 increases to 5 and the numbers to the right of it become zeros.
