3. Multiplication Operation
The multiplication operation is the core arithmetical process in determining what constitutes 30 percent of 1200. It serves as the direct mechanism by which the proportional value is extracted from the whole. The prior steps of converting the percentage to a decimal (0.30) prepares the data for this operation, wherein 0.30 is multiplied by 1200. This multiplication directly yields the value that corresponds to 30 percent of the original number. Without this operation, the process of calculating a percentage would remain incomplete, resulting in an undefined proportional value. Real-world examples include calculating sales tax (e.g., 6% sales tax on a $1200 purchase), where the multiplication operation determines the tax amount to be added to the original price, or determining the employee contribution to a retirement fund (e.g., 30% of a $1200 bonus), where the multiplication operation provides the exact contribution amount.
Further analyzing the practical applications reveals that the multiplication operation extends beyond simple arithmetic. In statistical analysis, it is used to calculate weighted averages, where individual values are multiplied by their corresponding weights. Similarly, in financial modeling, it’s used to forecast future earnings based on percentage growth rates applied to existing revenues. The accuracy of the multiplication operation is paramount; any errors in this step propagate through subsequent calculations, potentially leading to inaccurate financial reports, flawed statistical conclusions, or misinformed business decisions. In engineering contexts, calculations of stress and strain on materials often involve percentages of the materials’ tensile strength; here again, the multiplication operation is indispensable.
In conclusion, the multiplication operation is not merely a step within the broader calculation but the critical process by which the proportional value of 30 percent of 1200 is realized. Its importance lies in its ability to accurately quantify the designated portion, with applications spanning diverse fields from finance to engineering. A clear comprehension of this operational role is essential for anyone involved in quantitative analysis and decision-making based on numerical data.
4. Resultant Value

The calculation itself serves as the cause, and the resultant value is the effect. Without accurately determining the resultant value, the calculation remains incomplete and lacks practical significance. For example, in a business context, if a product costs $1200 and a 30% discount is offered, the resultant value ($360) represents the monetary amount of the discount. Inaccurate calculation of the resultant value directly impacts pricing strategies, profitability assessments, and financial reporting.
The significance of the resultant value is further emphasized in various quantitative analyses. In statistical modeling, if a dataset consists of 1200 observations and a researcher needs to isolate the top 30% based on a specific metric, the resultant value defines the threshold or boundary. Understanding the resultant value facilitates informed decision-making, resource allocation, and performance evaluation. In engineering applications, calculating stress tolerances often involves percentages of material strength. Determining 30% of a material’s maximum stress limit is crucial for ensuring structural integrity and preventing failure. The resultant value here becomes a critical safety parameter.
In summary, the resultant value is an indispensable component of the calculation process, providing the quantifiable answer and enabling practical application in diverse fields.
