What is rounding to a whole number?

When you round numbers, you are always rounding to a particular place value, such as the nearest thousand or the nearest ten. Whether you round up or round down usually depends on which number is closest to your original number. When a number is halfway between the two possible numbers, round up to the larger number.

How do you round up to the nearest whole number?

So in example 1 you need to round 73.2754 to the nearest whole number. Since the number in the tenths column is less than 5 the number is rounded down to 73. In example 2 you will need to round 276.72185 to the nearest whole. Since the number in the tenths column is 5 or above then you round the number up to 277.

What is 3.6 rounded to the nearest whole number?

3.57 rounded to the nearest whole number is 4. 3.57 rounded to 1 decimal place is 3.6 . Locate the right hand digit to the one which needs to be rounded. If that digit is 5 or more ie 3.55 or more, round up to 3.6 .
