A percentage represents a part out of 100. It is a way to express a number as a fraction of 100. In percentage problems, you often need to find a certain percentage of a number or figure out what percentage one number is of another.

To solve percentage problems, you can use the formula: Percentage = (Part / Whole) × 100

Examples:

Example 1: Finding a Percentage of a Number
What is 25% of 200?
Set up the calculation:
25% × 200 = (25 / 100) × 200 = 50
So, 25% of 200 is 50.

Example 2: Finding the Percentage
If you scored 18 out of 20 on a test, what is your percentage score?
Use the formula:
Percentage = (18 / 20) × 100 = 0.9 × 100 = 90%
Your percentage score is 90%.

Percentage problems are useful in many real-life situations, such as calculating discounts, tax, or interest rates.
