19.98 rounded to the nearest whole number is 20. In the number 19, 9 round the 1 to a 2 and the 9 becomes a 0 because of the 9 behind the decimal. OR You could think of a percent being 100. 98 is only 2 numbers away from 100 and thus you can round 19 up to 20.
The answer is 20. To make problems like this easier for you to understand, if the number is greater than 5 round up. If the number is 4 or less, round down. I hope you get what I am saying.
