At its core, a percentage is just a way of expressing a number as a fraction of 100. The word "percent" literally means "per hundred." So, 25% means 25 out of every 100.
Three Common Percentage Problems
Most percentage calculations fall into one of three categories. Let's explore each one:
- Finding a Percentage of a Number: This is figuring out what a specific percentage of a given number is. For example, what is 15% of 200?
- Finding What Percentage One Number is of Another: This involves determining what percentage one number represents of another number. For example, 30 is what percent of 150?
- Calculating Percentage Increase or Decrease: This is about finding the percentage change between two numbers. For example, what is the percentage change from 80 to 100?

Manual Calculation Methods (For the Curious)
If you're interested in understanding the math behind the calculations, here's a brief overview:
- Finding X% of Y: Multiply Y by (X/100). Example: 15% of 200 = 200 * (15/100) = 30
- Finding What Percent X is of Y: Divide X by Y and multiply by 100. Example: 30 is what percent of 150? (30/150) * 100 = 20%
- Calculating Percent Change: ((New Value - Old Value) / Old Value) * 100. Example: Change from 80 to 100? ((100-80)/80) * 100 = 25%
