The term "percentage" comes from the Latin per centum, meaning "by the hundred." A percentage is essentially a fraction with 100 as the denominator. In simpler terms, it's the relationship between a part and a whole, where the whole is always considered to be 100. For example, if a student scores 75 out of 100 on a test, their score is 75%.
Three Common Percentage Problems Solved Easily
Percentages show up everywhere, and solving them doesn't have to be a headache. Our percentage calculator is designed to tackle three common types of percentage problems:
- Finding what percent of a number is: What is 15% of 200?
- Determining what percentage one number is of another: 30 is what percent of 150?
- Calculating percentage increase or decrease: What is the percentage change from 80 to 100?
With our tool, solving these problems is as easy as entering the numbers and hitting 'calculate'. No more long formulas or manual calculations!
The Percentage Formula: A Quick Review
Even with a handy calculator, it's good to understand the underlying formula. The basic percentage formula is:
Percentage = (Value / Total Value) × 100
Let's say you want to find out what percentage of a class is made up of girls. If there are 10 girls in a class of 40 students, the calculation would be:
Percentage of girls = (10 / 40) × 100 = 25%
Examples of Using the Percentage Formula
- Discounts: If an item originally priced at $50 is on sale for $15 off, what's the discount percentage?
- Tips: You want to leave a 20% tip on a restaurant bill of $35. How much should you tip?
- Market Share: A company has sales of $2 million in a market valued at $10 million. What is the company's market share percentage?
