A percentage is a way of expressing a number as a fraction of 100. It is denoted using the percent sign (%). Percentages are used to compare proportions and are widely applicable in various fields such as finance, statistics, and everyday life. For example, if you have 25 apples out of a total of 100 apples, you can say you have 25% of the apples.

Why percentage is important?

The concept of percentage helps simplify complex fractions and makes it easier to understand and communicate proportions. For instance, rather than saying you scored 0.85 on a test, you can say you scored 85%, which is more intuitive and easier to grasp.

Percentage formula

To calculate a percentage, you divide the part by the whole and then multiply by 100. For example, to find out what percentage 50 is of 200, you calculate: (50200)×100=25%\left( \frac{50}{200} \right) \times 100 = 25\%(20050​)×100=25%

Percentages are essential in various real-world applications, including calculating interest rates, understanding discounts, analyzing data trends, and measuring growth. They provide a straightforward and universally understood way to express comparisons and changes in quantities.
