Understanding Percentages:
Percentages represent a part of a whole, expressed as a fraction of 100. They provide a standardized way to compare quantities, making it easier to understand proportions and relationships.
Calculating 10% of 33:
- Convert the percentage to a decimal: Divide 10% by 100, giving you 0.10.
- Multiply the decimal by the whole number: Multiply 0.10 by 33, resulting in 3.3.
Therefore, 10% of 33 is 3.3.
Practical Applications of Percentages:
- Discounts: Stores often offer discounts on items, such as "20% off." To calculate the discount, multiply the original price by the decimal form of the discount (0.20).
- Interest Rates: Banks and financial institutions use percentages to determine interest earned on savings accounts or interest charged on loans.
- Taxes: Governments levy taxes on income, goods, and services, typically expressed as percentages.

- Adding percentages directly: Adding percentages directly is only valid if they are based on the same whole. For example, 10% of 100 + 10% of 200 does not equal 20%.
Tips for Mastering Percentages:
- Practice regularly: The more you practice, the more comfortable you will become with percentage calculations.
