144/720 = 20%
A fraction like 144/720 can represent a discount, test score, survey result, or part of a group. For example, if 144 out of 720 shoppers choose a certain product, that is 20% of the shoppers.
To picture 20% quickly, think of one-fifth of a whole. On a bar or circle divided into five equal parts, 20% would fill one part, so it is noticeably less than half but more than a small sliver.
A common mistake is to think 20% means 20 out of every 100 items only when the total is exactly 100. The same proportion can describe 144 out of 720, even though neither number is 20 or 100.
