Rounding Decimals

Rounding is the process of adjusting the value of a number to make it simpler and easier to work with, while keeping it close to the original value.

Rounding to the nearest whole number means adjusting a decimal number to the closest whole number. If the decimal is 0.5 or higher, round up; if it's less than 0.5, round down.

To round a number to the nearest ten, look at the digit in the ones place. If it's 5 or more, round up; if it's less than 5, round down.

The nearest whole number to 4.18 is 4.

The nearest dollar to $0.33 is $0.00.

The rule for rounding decimals is to look at the digit immediately to the right of the place value you are rounding to. If it's 5 or more, round up; if it's less than 5, round down.

The number 43.4 rounds to 40 when rounded to the nearest ten.

The nearest whole number to 17.25 is 17.
