Percentages are a fundamental part of our daily lives. They allow us to easily compare and understand portions of a whole, making them incredibly valuable in various fields, from finance and business to science and everyday decision-making. “What is 15 of 60?” is not just a simple question; it’s a key to understanding the language of percentages and how they apply to our world.

Understanding the Concept

Before diving into the specifics of calculating “15 of 60,” let’s first grasp the core concept of percentages. The word “percent” comes from the Latin “per centum,” meaning “out of one hundred.” In essence, a percentage represents a fraction out of a hundred. Therefore, 15% can be written as 15/100 or 0.15 in decimal form.

Imagine a pizza cut into 100 slices. If you have 15 slices, you have 15% of the whole pizza. This visual representation helps illustrate how percentages represent a proportional part of a whole.

Methods for Calculating Percentages

There are a few easy ways to calculate what 15 of 60 is. Let’s explore each approach step by step:

1. The Fraction Method

• Step 1: Express the percentage as a fraction. In this case, 15% becomes 15/100.
• Step 2: Multiply the fraction by the whole number, which is 60. So, (15/100) * 60.
• Step 3: Simplify the equation: (15 * 60) / 100 = 900/100
• Step 4: Divide the numerator by the denominator: 900 / 100 = 9.

Therefore, 15% of 60 is 9.

2. The Decimal Method

• Step 1: Convert the percentage into a decimal by dividing it by 100. 15% divided by 100 is 0.15.
• Step 2: Multiply the decimal by the whole number. So, 0.15 * 60 = 9.

This method offers a more direct approach using decimal representation.

3. The Proportion Method

• Step 1: Set up a proportion with the percentage and the whole number. 15/100 = x/60. Here, ‘x’ represents the unknown portion we need to calculate.
• Step 2: Cross-multiply to solve for ‘x’: 15 60 = 100 x.
• Step 3: Simplify: 900 = 100x.
• Step 4: Divide both sides by 100: 900/100 = x.
• Step 5: Therefore, x = 9.

The Proportion Method provides a visual representation of the relationship between the percentage and the whole number.

Real-World Applications of Percentage Calculations

Now that we understand how to calculate percentages, let’s explore some real-life applications:

1. Shopping Discounts

Imagine you’re looking at a dress priced at $60 with a 15% discount. Using the methods we discussed, you can quickly calculate the discount: 15% of $60 is $9. Subtracting the discount from the original price results in a final cost of $51.

2. Tip Calculations

When dining out, it’s common courtesy to leave a tip for your server. A standard tip is 15% of the total bill. If your bill totals $60, a 15% tip would be $9.

3. Interest Calculation

If you’re saving money in a bank account that earns interest, the interest rate is usually expressed as a percentage. Let’s say your bank offers a 15% annual interest rate on your savings. If you have $60 saved, you’ll earn $9 in interest at the end of the year.

4. Survey Results

Surveys often present data in the form of percentages to analyze public opinion or trends. For example, if a survey shows that 15% of respondents prefer a particular brand of coffee, you can extrapolate that if there were 60 participants, 9 people would have chosen that coffee brand.

5. Grade Calculations

In educational settings, percentages are used to express grades. For instance, if a student scores 15 out of 60 marks on a test, their score would be a 25% (15/60 * 100).
