Mastery of percentages is essential not only for topics like profit and loss, interest calculations, and ratio but also for everyday applications in commerce, finance, and statistics. By consistent practice, applying logical steps, and solving varied examples, students can confidently handle percentage problems and strengthen their mathematical reasoning and analytical skills. The percentage is a way of expressing a part or proportion of a whole as a fraction of 100. It is a commonly used concept in mathematics, statistics, finance, and everyday life. The term "percent" means "per hundred." It is denoted by the symbol "%". When we say something is "x percent," it means x parts out of 100 parts. For example, if you scored 85% on a test, it means you obtained 85 marks out of 100. Similarly, if a store offers a 20% discount on a product, it means the price of the product is reduced by 20% of its original price.

The percentage can be calculated using the following formula:
Percentage = (Part/Whole) * 100
Where "Part" represents the value or quantity you are referring to, and "Whole" represents the total value or quantity.
To find the percentage, you divide the part by the whole, and then multiply the result by 100 to express it as a percentage.
