Simply put, a percentage represents a portion of a whole, often denoted by the symbol "%." For instance, if you have 50%, it means you have half of something.
2. Basic Percentage Calculations To calculate a percentage, you typically multiply the given number by the percentage and then divide by 100. For example, if you want to find 20% of 50, you'd multiply 50 by 20 and then divide by 100.
3. Calculating Percentage Increase If you want to find the percentage increase between two numbers, subtract the original number from the new number, divide by the original number, and then multiply by 100 to get the percentage.
4. Determining Percentage Decrease Similarly, to find the percentage decrease, follow the same steps as for increase but with subtraction reversed. Subtract the new number from the original, divide by the original, and then multiply by 100.
5. Finding the Percentage of a Number To find what percentage one number is of another, divide the first number by the second, and then multiply by 100. This gives you the percentage.
6. Using Percentages in Sales Percentages play a crucial role in sales, especially when calculating discounts or markups. Knowing how to use percentages effectively can help you make informed decisions and snag the best deals.

8. Working with Compound Interest Compound interest involves applying interest to the initial amount, as well as the accumulated interest from previous periods. Calculating compound interest often requires using percentages iteratively.
9. Tips for Efficient Percentage Calculation Break It Down: Complex calculations can be simplified by breaking them into smaller, manageable steps.
