### Rounding decimals at a glance

Rounding decimals involves approximating a decimal number to make it easier to read and work with. It is common to round decimals to the nearest whole number, nearest tenth, nearest hundredth or nearest thousandth.

In order to round decimal numbers, we can picture where the number would appear on a number line to help us decide whether to round up or down. In general numbers 5 or greater round up and numbers 4 or less round down. For example, when rounding numbers to 2 decimal places, we look at the next decimal place value, the thousandths. If the number in the thousandths column is 5 or greater we round up. If it is 4 or less we round down.

As an alternative to rounding to a given number of decimal places, we could round to a given number of significant figures.
