What Are Percentages?


A percentage is a special ratio in which the second term of the ratio is always 100. By expressing a number as a percentage you are reflecting how many times it occurs in relation to 100 times. As an example: 3/4 is expressed as 75/100 or 75%. In other words, there would be 75 out of 100 occurrences, people, places, etc.
