Calculating a percentage of a given number is a fundamental mathematical operation with broad applicability. Determining 25% of 800 involves finding a quarter of the total amount. This is achieved by multiplying the decimal equivalent of the percentage (0.25) by the base number (800). The result of this calculation is 200.
Understanding percentage calculations is important for various real-world applications. It is essential in financial contexts such as calculating discounts, interest rates, and profit margins. In statistical analysis, percentages are used to represent proportions and compare datasets. Historically, the concept of percentages has been used for centuries in trade, commerce, and taxation to express ratios and proportions in a standardized manner.
