A percentage is a way of expressing a number as a fraction of 100. It is often denoted by the symbol “%”. This simple yet powerful concept is essential in various aspects of life, from calculating students’ grades to analyzing financial statements.

### The Basic Formula

The fundamental formula to calculate a percentage is:

]

To break this down:

• Part: The specific quantity you want to find the percentage of.
• Whole: The total quantity.

For example, if you scored 45 out of 60 on a test, your percentage would be calculated as follows:

[

\text{Percentage} = \left( \frac{45}{60} \right) \times 100 = 75%

For instance, if an item costs $50, a 30% discount means you save: [ \text{Savings} = 50 \times 0.30 = 15 \text{ dollars} ] Hence, the final price would be$35.

Sales taxes can vary, and calculating them can sometimes lead to confusion. Suppose you’re purchasing a set of items costing $100 and the sales tax is 8%. The total amount you will pay can be calculated as follows: [ \text{Tax Amount} = 100 \times 0.08 = 8 \text{ dollars} ] [ \text{Total Price} = 100 + 8 = 108 \text{ dollars} ] ### 3.
