Understanding Percentages
A percentage is a way to express a number as a fraction of 100. The word "percent" comes from the Latin "per centum," meaning "by the hundred." It's a standard way of expressing the relative size of one quantity to another.
For instance, if you have 50 apples and 20 of them are red, then 20/50 = 40/100, so 40% of your apples are red. This concept can be applied to various scenarios like calculating markup percentage or understanding discounts during sales (percent off calculator app).

Percentage Formulas Explained
While our calculator does the heavy lifting, understanding the underlying formulas can be beneficial:

- Percentage of One Number to Another: (Part / Whole) * 100
- Percentage Change: ((New Value - Old Value) / Old Value) * 100
Real-World Applications
