The Basics of Percentages

A percentage is essentially a fraction or a ratio expressed as a part of 100. It provides a standardized way to represent proportions and compare different quantities.

Calculating the Percentage: The Formula

The core concept in how to find out the percentage of two numbers is quite simple. The formula is:

Percentage = (Part / Whole) * 100

  • Part: The smaller number or the value you want to express as a percentage.
  • Whole: The larger number or the total value.

Step-by-Step Example

Let's say you want to find out what percentage 30 is of 150. Here's how to apply the formula:

  1. Identify the "Part" and the "Whole": In this case, 30 is the "Part" and 150 is the "Whole".
  2. Divide the "Part" by the "Whole": 30 / 150 = 0.2
  3. Multiply the result by 100: 0.2 * 100 = 20
  4. Therefore: 30 is 20% of 150.

Real-World Applications

This calculation is useful in many scenarios:

  • Discounts: Figuring out the discount percentage on a sale item.
  • Test Scores: Calculating your score on a test.
  • Financial Analysis: Determining the percentage of your income spent on rent.
  • Business: finding the percentage increase or decrease in sales from one period to another
