In mathematics, a percentage is 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." Therefore, percentages are used to represent parts of a whole, where the whole is considered to be 100. Percentages are often denoted by the symbol "%", making them easily recognizable and applicable in various contexts.
The Percentage Formula: A Simple Equation
The core concept of calculating amount in percentage revolves around a simple algebraic equation:
Part = Percentage × Whole
This formula can be rearranged depending on what you are trying to find:
- Finding the Part: When you know the percentage and the whole, you can calculate the part. (e.g., What is 15% of 200?)
- Finding the Percentage: If you know the part and the whole, you can calculate the percentage. (e.g., 30 is what percent of 150?)
- Finding the Whole: If you know the part and the percentage, you can calculate the whole. (e.g. 20 is 25% of what number?)
Calculating Percentage Increase or Decrease
Another common application of percentages is calculating the increase or decrease between two values. Here's how:
- Find the difference: Subtract the original value from the new value.
- Divide by the original value: Divide the difference by the original value.
- Multiply by 100: Multiply the result by 100 to express it as a percentage.
For example, if a price increases from $80 to $100:
- Difference: $100 - $80 = $20
- Divide by original: $20 / $80 = 0.25
- Multiply by 100: 0.25 × 100 = 25%
This represents a 25% increase.
