Understanding Percentages
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% is equivalent to 25/100, 0.25, or one-quarter.
Three Common Percentage Problems
Most percentage calculations fall into three main categories. Here's how to solve each:
1. Finding What Percent of a Number Is
This is the classic "What is X% of Y?" problem. For example, what is 15% of 200?
Formula: Percentage × Number = Result
Example: 15% of 200 = 0.15 * 200 = 30
Easier Solution: Skip the manual math and instantly find the answer with our percentage calculator! Simply enter the percentage and the number, and let our tool do the work.
2. Finding What Percentage One Number Is of Another
This type answers the question, "X is what percent of Y?" For example, 30 is what percent of 150?
Formula: (Part / Whole) × 100 = Percentage
Example: (30 / 150) × 100 = 20%
Easier Solution: Our calculator makes this even simpler! Just enter the two numbers, and you'll immediately see the percentage.
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?
Formula: [(New Value - Old Value) / Old Value] × 100 = Percentage Change
Example: [(100 - 80) / 80] × 100 = 25%
Easier Solution: Use our percentage calculator to determine increase or decrease between one number from the other. It handles the math for you, providing the percentage change instantly.
