Rounding decimals refer to the rounding of decimal numbers to a certain degree of accuracy. We can round decimals to the nearest wholes, tenths or hundredths when having exact values isn’t important. A rounded number has almost the same value as the original number, but it is a bit less exact. There are certain rules to follow when rounding a decimal number. Put simply, if the last digit is greater, or less than 5, round the previous digit down. However, if it’s greater, or equal to 5, you should round the previous digit up. The next topic contains a video explaining in detail how this process works.
