Many common percentage problems can be categorized into three main types:
- Finding a percentage of a number: What is X% of Y? (e.g., What is 15% of 200?)
- Determining what percentage one number is of another: X is what percent of Y? (e.g., 30 is what percent of 150?)
- Calculating percentage increase or decrease: What is the percentage change from X to Y? (e.g., What is the percentage change from 80 to 100?)
How to Calculate the Percentage Between Two Numbers
The core concept involves understanding the relationship between a part and a whole. Here's a breakdown of how to approach these calculations:
- Identify the two numbers. Determine which number is the "part" and which is the "whole".
- Divide the "part" by the "whole". This gives you a decimal value.
- Multiply by 100. This converts the decimal into a percentage.
Formula: (Part / Whole) * 100 = Percentage
Example: If you want to know what percentage 30 is of 150:
(30 / 150) * 100 = 20%
Therefore, 30 is 20% of 150.

Using Percentage Change to Check the Relationship
To find the percentage increase or decrease between two numbers:
- Find the difference between the two numbers.
- Divide the difference by the original number.
- Multiply by 100.
Formula for Percentage Change: [(New Value - Old Value) / Old Value] * 100
A positive result indicates a percentage increase, while a negative result indicates a percentage decrease.
