Determining a specific percentage of a given number is a common mathematical operation. In this instance, the objective is to calculate what quantity constitutes twenty percent of forty-eight. This involves converting the percentage into a decimal or fraction and then multiplying it by the whole number to find the corresponding portion. For example, one could express twenty percent as 0.20 and multiply it by 48 to arrive at the solution.
The ability to calculate percentages is fundamental across numerous disciplines. From finance and accounting, where it is used to determine interest rates, profit margins, and tax calculations, to everyday life, where it aids in understanding discounts, sales, and proportional distributions, this calculation offers practical utility. Historically, the concept of percentages has evolved alongside the development of commerce and mathematical notation, providing a standardized way to express proportions and ratios.
