Percentage is a way of expressing a number as a fraction of 100. It is often represented by the symbol "%". For example, if you score 80 out of 100 in a test, your percentage score would be 80%. Percentages are commonly used to describe a part of a whole, where the whole is represented as 100%.

Percentage can also be used to represent a change in quantity over time, such as an increase or decrease in a value. For example, if the price of a product has increased from $10 to $12, the percentage increase can be calculated as (12-10)/10 x 100 = 20%.

Percentage is used in a variety of fields, including education, finance, and statistics. It is an important tool for analyzing and comparing data, as well as for setting goals and measuring progress.

Short version.

Calculating percentage involves finding the ratio of a given number to a total of 100. The formula for calculating percentage is:

Percentage = (Given Number/Total) x 100

For example, let's say you received 85 marks out of 100 in an exam. To calculate your percentage, you can use the formula as follows:

Percentage = (85/100) x 100 = 85%

Therefore, your percentage in the exam is 85%.

Long version.

Percentage is a widely used mathematical concept that expresses a number as a fraction of 100. In other words, it represents a part of a whole, with the whole being equal to 100%.

Calculating a percentage involves finding what fraction of a given quantity a certain number represents. This can be done by dividing the given number by the total quantity and then multiplying the result by 100.

For example, if there are 50 apples in a basket and you want to know what percentage of the basket is represented by 20 apples, you can use the following formula:

Percentage = (Number of apples / Total apples) x 100

Percentage = (20 / 50) x 100

Percentage = 0.4 x 100

Percentage = 40%

So, 20 apples represent 40% of the total apples in the basket.

Percentages are used in a variety of contexts, from calculating test scores to calculating discounts on purchases. Being able to calculate percentages is an important skill in many areas of life, from finance and business to science and engineering.

To calculate percentage, you need to know the total possible score and the actual score achieved. Once you have these two values, you can use the following formula:

percentage = (actual score / total possible score) x 100

For example, if a student scores 80 out of 100 on an exam, the percentage calculation would be:

percentage = (80 / 100) x 100 = 80%

Percentages are often used to express grades, test scores, and other performance metrics. They can also be used to compare two or more values in terms of their relative performance.

It's important to note that percentage is just one way to express a value relative to a total. Other common ways include ratios, fractions, and decimals. In some cases, one format may be more appropriate than another depending on the context and the specific values involved.
