Calculating a percentage of a given number is a fundamental mathematical operation with broad applications. In the specific instance of determining 20% of 350, the calculation involves multiplying 350 by the decimal equivalent of 20%, which is 0.20. The resultant value represents one-fifth of the original quantity. The calculation is as follows: 350 * 0.20 = 70. Therefore, 20% of 350 is 70.
The ability to accurately calculate percentages is crucial in various contexts, spanning personal finance, business analysis, and statistical interpretation. In business, understanding percentage discounts, profit margins, or growth rates is essential for informed decision-making. In personal finance, calculating interest rates, savings returns, or budget allocations relies heavily on percentage calculations. The concept provides a standardized method for representing proportions and comparing relative magnitudes, facilitating effective communication and analysis.
