How do you know when to round up decimals ?When dealing with decimal numbers, rounding is an important concept that everyone should master. Rounding is useful in different situations: rounding to pay bills or in an academic setting to find out the estimate of the average score of students in a class.Rounding decimals consists of rounding a decimal number to a certain number of decimal places, to save time and help us express really long numbers in shorter terms. 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 less than 5, round the previous digit down. However, if it’s 5 or more than you should round the previous digit up. So, if the number you are about to round is followed by 5, 6, 7, 8, 9 round the number up. And if it is followed by 0, 1, 2, 3, 4 round the number down. Write it down
