At its core, a percentage is a way of expressing a number as a fraction of 100. The word "percent" literally means "per hundred." So, 25% simply means 25 out of every 100. This makes percentages a convenient way to compare different quantities relative to a common base.
The Basic Percentage Formula
The most fundamental way to calculate a percentage involves three values:
- Part: The specific quantity you're interested in.
- Whole: The total quantity or reference value.
- Percentage: The part expressed as a fraction of the whole, multiplied by 100.
The formula to find a percentage is:
Percentage = (Part / Whole) × 100
Three Common Percentage Problems & Solutions
While the basic formula remains the same, percentage problems often fall into one of these categories:
1. Finding What Percent of a Number Is
Problem: What is P% of X?
Formula: Y = (P/100) * X
Example: What is 15% of 200?
Solution: Y = (15/100) * 200 = 30. So, 15% of 200 is 30.
2. Finding What Percentage One Number Is of Another
Problem: Y is what % of X?
Formula: P = (Y / X) * 100
Example: 30 is what percent of 150?
Solution: P = (30 / 150) * 100 = 20%. So, 30 is 20% of 150.
3. Calculating Percentage Increase or Decrease
Problem: Find the percentage change from Value 1 to Value 2.
Formula: Percentage Change = ((Value 2 - Value 1) / Value 1) * 100
Example: What is the percentage increase from 80 to 100?
Solution: Percentage Change = ((100 - 80) / 80) * 100 = 25%. So, there is a 25% increase.
