Determining a percentage of a given number is a fundamental mathematical operation. In the specific case of finding 20 percent of 110, the calculation involves multiplying 110 by 0.20 (the decimal equivalent of 20 percent). This results in a value of 22. This process represents a direct application of percentage calculation principles. An example of this calculation is figuring out a discount; if an item originally costs $110 and is 20% off, the discount amount is $22.
This type of calculation holds importance across various domains, including finance, retail, and data analysis. It facilitates understanding proportional relationships and enables informed decision-making. Historically, the concept of percentages has been integral to trade and commerce, allowing for standardized methods of representing fractions and proportions. The ability to quickly and accurately calculate such values is a valuable skill.
