What are Percentages?

Percentages are a fundamental concept used in various fields to express proportions or ratios. They are commonly employed to convey the relative value or significance of a particular quantity compared to a whole or a given reference point.

In simple terms, a percentage is a way to express a part of a whole as a fraction of 100. It is denoted by the symbol "%". For example, if you score 80% on a test, it means you obtained 80 marks out of every 100 possible. Similarly, when a price is reduced by 20%, it implies a discount of 20 units for every 100 units of the original price.

Percentages help to simplify complex data and make it easier to comprehend and compare. They are extensively utilized in statistics, economics, finance, and everyday life. Whether it's analyzing market shares, calculating taxes, interpreting survey results, or understanding statistical trends, percentages serve as a valuable tool for summarizing information and making informed decisions.

Understanding percentages is essential for data literacy as it enables individuals to interpret and communicate numerical information accurately. By grasping this concept, you will gain the ability to make sense of data, distinguish between relative values, and evaluate the impact of changes in different contexts.
