1. Simple Percentage (What is X% of Y?)

This is the most basic form. Use this to calculate sales tax, tips, or simple discounts.
Example: What is 20% of 150? Answer: 30.

2. Reverse Percentage (X is what % of Y?)

Use this to find out your score on a test or what portion of a budget you have used.
Example: 20 is what % of 80? Answer: 25%.

3. Percentage Change (Increase/Decrease)

Perfect for tracking growth, profit margins, or price drops.
