Procentai

Procentai is the Lithuanian word for percentages. In English, the term percent or percentage denotes a ratio of a quantity to a hundred. Percentages allow comparing amounts across different bases and expressing changes in a standardized form. The symbol % is used globally.

Calculation: To find a percentage of a number, multiply the number by the percentage divided by 100. For example, 25% of 200 equals 0.25 × 200 = 50. To express a number as a percentage of another, divide the first by the second and multiply by 100. Percentage change between two values is ((new − old) / old) × 100. A change of 25 percentage points is not the same as a 25 percent change; the former refers to an absolute difference in percentage points, the latter to a relative change.

Applications: Percentages are used in finance (interest rates, discounts, taxes), statistics (proportions, survey results), economics, and demographics. They are also used in quality control and rating systems.

Alternative representations: Percentages can be written as fractions or decimals. 0.75 equals 75%, 1/4 equals 25%, etc. The base for a percentage must be clear to avoid misinterpretation.

Origin: The term comes from Latin pro centum, meaning for each hundred. The concept is expressed in many languages, with local words like procentai in Lithuanian where the plural refers to multiple percentages.
