Rounding Off Decimals
Rounding off deals with making a number simpler but keeping its value close to what it was. To round off numbers properly, you should be familiar with the different place value and rules in rounding. Below are the rules for rounding off numbers:
- Look for the rounding digit. If the digit right beside it is 5, 6, 7, 8 or 9, round up. Add 1 to the rounding digit.
- Look for the rounding digit. If the digit right beside it is 4, 3, 2, 1 or 0, round down. The rounding digit remains the same.
Let us now round off the given decimals above by applying the rules.
