Percent Explanation Meaning Math What is the meaning of percentages?

A percentage is a number that indicates that one number is a percentage of another number, also called a percentage or percentage. Percentages are usually not written as fractions, but are represented by the symbol "%" called the percent sign). Percentages are widely used in industrial and agricultural production, science and technology, and various experiments, especially in surveys, statistics, analysis and comparison.

Percentages (also known as percentages or percentages) can only represent fractions, not specific quantities, so they cannot be used in units.

Although the percentage is denominated by 100, the numerator can be greater than 100, for example, 200% represents 2 times the original number. For example, if a company's net profit last year was 1 million yuan, and this year's net profit is 1.2 million yuan, it can be expressed as "this year's net profit is 20% higher than last year", or it can be written as "this year's net profit is 120% of last year", but this is rarely used. Percentages can sometimes be misleading, and many people think that an increase in one percentage will be offset by the same falling percentage, such as a 50% increase from 100, which is equal to 100 + 50, or 150.

And a 50% drop from 150 is 150-75, which equals 75. The end result is less than the original number 100. The numerator of the percentage can also be a decimal.
