Understanding Percentages
Before diving deeper, let's quickly recap what a percentage actually represents. A percentage is simply a way of expressing a number as a fraction of 100. The word "percent" comes from the Latin "per centum," meaning "out of one hundred." So, when we say "15%," we mean "15 out of every 100."
How the Percentage Calculator Works
The PercentageFinder.org calculator uses the fundamental percentage formula to solve various problems. While the formula can be expressed in different ways, the core principle remains the same:
Part / Whole = Percentage / 100
Depending on the problem you're trying to solve, the calculator rearranges this formula to isolate the unknown variable. Let's look at some examples:
- Finding a percentage of a number: What is 25% of 80? Here, you're looking for the "part." The calculator uses the formula: Part = (Percentage / 100) * Whole. In this case, Part = (25 / 100) * 80 = 20.
- Finding what percentage one number is of another: 20 is what percent of 80? Here, you're looking for the "percentage." The calculator uses the formula: Percentage = (Part / Whole) * 100. In this case, Percentage = (20 / 80) * 100 = 25%. You can read more about different percentage change approaches from the article discussing how to calculate percentage change between two numbers.
- Finding the whole when you know a percentage and a part: 25 is 20% of what number? Here, you're looking for the "whole." The calculator uses the formula: Whole = Part / (Percentage / 100). In this case, Whole = 25 / (20 / 100) = 125.
