At the heart of our exploration lies the question: what is 15 percent of 500? While the answer might seem simple on the surface, the pathway to uncovering it unlocks a treasure trove of understanding about percentages, fractions, and their profound connection to our world.
Understanding the Basics: A Primer on Percentages
Percentages represent parts of a whole, expressed as a fraction of 100. Put simply, “percent” means “out of one hundred.” The symbol “%” is used to denote percentages.
Understanding percentages begins with grasping the concept of fractions. A fraction represents a part of a whole, with two components: the numerator (the top number) and the denominator (the bottom number). The numerator indicates the number of parts being considered, while the denominator denotes the total number of parts in the whole. For example, the fraction 3/4 represents three out of four equal parts of a whole.
Connecting the Dots: Percentages, Fractions, and Decimals
Percentages, fractions, and decimals are intimately related. They are simply different ways of representing the same value. To convert a percentage to a fraction, divide the percentage by 100 and simplify the resulting fraction. For instance, 15% can be expressed as the fraction 15/100, which simplifies to 3/20.
Conversely, to convert a fraction to a percentage, divide the numerator by the denominator and multiply the result by 100. For example, the fraction 3/20 can be converted to a percentage by dividing 3 by 20, which gives us 0.15. Multiplying 0.15 by 100 gives us 15%, confirming our earlier conversion.
Deciphering the Mystery: Calculating 15 Percent of 500
Now, let’s delve into the pivotal question: what is 15 percent of 500? We can approach this problem in a few different ways.
Method 1: Using Fractions
- Express 15% as a fraction: 15/100
- Multiply the fraction by 500: (15/100) * 500 = 75
Method 2: Using Decimals
- Convert 15% to a decimal: 15/100 = 0.15
- Multiply the decimal by 500: 0.15 * 500 = 75
Method 3: Using Proportions
- Set up a proportion: 15/100 = x/500
- Solve for x: 100x = 7500
- Simplify: x = 75
All three methods lead us to the same answer: 15 percent of 500 is 75.
