At its core, a percentage is simply 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.
The Basic Formula
The most common way to find a percentage of an amount is using this formula:
(Percentage / 100) * Amount = Result
Let's break it down with an example. What is 15% of 200?
- Convert the percentage to a decimal: Divide 15 by 100, which equals 0.15.
- Multiply the decimal by the amount: 0.15 * 200 = 30
Therefore, 15% of 200 is 30.
Three Common Percentage Problems Solved Easily
Percentages pop up in all sorts of situations. Here are three common scenarios you might encounter, and how to solve them:
1. Finding a Percentage of a Number
Like the example above, this is about determining a portion of a whole. For example, "What is 30% of 500?" Use the formula (Percentage / 100) * Amount = Result
2. What Percentage is One Number of Another?
Here, you want to know what proportion one number represents of another. For example, "30 is what percent of 150?" The formula is: (Part / Whole) * 100 = Percentage. (30 / 150) * 100 = 20%, so 30 is 20% of 150
3. Calculating Percentage Increase or Decrease
This involves finding the percentage change between two values. For example, "What is the percentage increase from 80 to 100?" First, find the difference (100 - 80 = 20). Then, divide the difference by the original number (20 / 80 = 0.25). Finally, multiply by 100 to get the percentage: 0.25 * 100 = 25%. The percentage increase is 25%.

Tips and Tricks
- Estimating: To quickly estimate 10% of a number, simply move the decimal point one place to the left. For example, 10% of 345 is approximately 34.5.
- Breaking it down: To find 20% of a number, calculate 10% first and then double it. This makes mental calculations faster.
- Understanding Fractions: Recognizing common percentage-fraction equivalencies (e.g., 50% = 1/2, 25% = 1/4) can simplify calculations. You can further explore fractions in our article about converting percentages to fractions.
