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, 25% means 25 out of every 100, or 25/100.
Three Common Percentage Problems
Most percentage problems fall into one of these three categories:
- Finding what percent of a number is: For example, "What is 15% of 200?"
- Determining what percentage one number is of another: For example, "30 is what percent of 150?"
- Calculating percentage increase or decrease: For example, "What is the percentage increase from 80 to 100?"
Solving Percentage Problems Manually
While our calculator can handle these problems instantly, understanding the manual calculation can be helpful.
1. Finding a Percentage of a Number
To find X% of Y, multiply Y by X/100. For instance, to find 15% of 200:
15/100 * 200 = 0.15 * 200 = 30
2. Finding What Percentage One Number is of Another
To find what percentage X is of Y, divide X by Y and multiply by 100. For instance, to find what percentage 30 is of 150:
(30 / 150) * 100 = 0.2 * 100 = 20%
3. Calculating Percentage Increase or Decrease
To find the percentage increase or decrease from an initial value (A) to a final value (B), use the formula: ((B - A) / A) * 100. For instance, to find the percentage increase from 80 to 100:
((100 - 80) / 80) * 100 = (20 / 80) * 100 = 0.25 * 100 = 25%
