Determining a percentage of a given number involves calculating a fraction of the whole. In this instance, finding 20% of 450,000 requires multiplying 450,000 by 0.20 (the decimal equivalent of 20%). This calculation yields a result of 90,000. For example, if 450,000 represents a total budget, then 90,000 would represent 20% of that budget.
Understanding percentage calculations is fundamental in various fields, including finance, statistics, and business. Accurate percentage calculations are crucial for budgeting, profit margin analysis, sales forecasting, and numerous other applications requiring precise numerical representation of proportions. The ability to perform such calculations efficiently contributes to informed decision-making and effective resource allocation. This concept has been consistently important throughout the history of quantitative analysis, with its applications evolving alongside advancements in mathematics and computing.
