ROUNDING OFF DECIMALS

Rounding off decimals is a technique used to estimate or aproximate values. We can around to any place.ROUND UP AND ROUND DOWN increase one digit or decrease one digit. If the next place beyond where we are terminating the decimal is greater than or equal to five we round up.



How to round down: if the number to the right of our terminating decimal place is four or less.

For example:

a) 3,84 Here we have a decimal number to round off to tenths. First of all if the next place beyond where we are terminating the decimal is less than five we will round down. So if the number is 3,84 we must round down to the eight.
