Determining a percentage of a number is a fundamental mathematical operation. In this specific instance, the objective is to calculate the numerical value that represents forty percent of the quantity one hundred and fifty. This type of calculation finds application in various real-world scenarios, such as determining discounts, calculating proportions, or understanding statistical data. For example, if an item priced at $150 is offered with a 40% reduction, the amount of the discount is found by this calculation.
The ability to compute percentages is valuable for financial literacy, budgeting, and understanding statistical data presented in proportional terms. Historically, the concept of percentages evolved from the need to standardize proportions for easier comparison and understanding. This standardization simplifies the interpretation of ratios and fractions, allowing for clear communication of relative quantities across different scales. For instance, understanding percentages is vital when analyzing economic growth rates or interpreting survey results.
