The core concept is simple: divide the "part" (the number you're expressing as a percentage) by the "whole" (the reference number) and then multiply by 100.
Percentage = (Part / Whole) x 100
For example, if you want to know what percentage 30 is of 150, you would perform the following calculation:
Percentage = (30 / 150) x 100 = 20%
Therefore, 30 is 20% of 150.
Real-World Examples
- Exam Scores: If you scored 75 out of 100 on a test, your percentage score is (75/100) * 100 = 75%.
- Discounts: If an item originally priced at $50 is on sale for $40, the discount percentage is (($50 - $40) / $50) * 100 = 20%.
- Market Share: If a company sells 40,000 units in a market where the total sales are 100,000 units, the company's market share is (40,000 / 100,000) * 100 = 40%.
- Financial Analysis: If a company's profit is $2 million on revenues of $10 million, the profit margin is ($2,000,000 / $10,000,000) * 100 = 20%.
