Detailed Explanation

To fully grasp What percent of 120 is 15?, it’s essential to understand the underlying principles of percentages. A percentage is a way to express a number as a fraction of 100. For example, 50% means 50 out of 100, or half. This concept allows us to compare values regardless of their absolute sizes. In the case of What percent of 120 is 15?, we are dealing with a ratio where 15 is the "part" and 120 is the "whole." The goal is to determine how many parts out of 100 this ratio represents.

The formula for calculating percentages is straightforward:
$ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 $
Applying this to our example, the "part" is 15, and the "whole" is 120. By dividing 15 by 120, we find the proportion of the whole that 15 occupies. Multiplying this result by 100 converts it

into a percentage, giving us the answer to What percent of 120 is 15? This process is not just a mathematical exercise; it’s a tool for making sense of proportions in real-world scenarios. For instance, if a company spends $15,000 out of a $120,000 budget on marketing, knowing the percentage helps assess the allocation of resources.

Understanding percentages also involves recognizing their relationship to fractions and decimals. For example, 15 out of 120 can be expressed as the fraction 15/120, which simplifies to 1/8. Converting this fraction to a decimal (0.125) and then to a percentage (12.5%) provides a clear and standardized way to interpret the ratio. This multi-step process highlights the interconnectedness of mathematical concepts and their practical utility.

Moreover, percentages are often used in comparisons. If two quantities are expressed as percentages, it becomes easier to compare them directly. For example, if one product has a 15% discount and another has a 20% discount, the percentages allow for an immediate comparison of the savings, regardless of the original prices. This ability to standardize comparisons is one of the reasons percentages are so widely used in fields like economics, statistics, and science.

In the context of What percent of 120 is 15?, the calculation reveals that 15 is 12.5% of 120. This means that if you were to divide 120 into 100 equal parts, 15 would occupy 12.5 of those parts. This perspective helps visualize the proportion and underscores the importance of percentages in breaking down complex ratios into manageable and interpretable units.
