Percentage is a way to express a relation between two numbers as a fraction of 100. In other words, the percentage tells us how one number relates to another. If we know that number A is 25% of number B, we know that A to B is like 25 is to 100 (one more transformation: A is four times smaller than B). This is Percentage Calculator's lesson on what is percentage.
But in money a percent is how many cents past the dollar the number is.
