So, let's dive in and explore the world of percentages together!
Introduction
When faced with a mathematical problem, it's important to break it down and understand what it is asking for. In this case, we are trying to find out what percentage 15 is of 75. By using simple calculations, we can determine the answer. Let's dive in and explore the steps to solve this problem!
Understanding Percentages
Before we proceed, let's quickly refresh our understanding of percentages. A percentage is a way of expressing a portion of a whole as a value out of 100. It is typically denoted by the symbol %. Therefore, when we say 15 percent, we mean 15 out of every 100.
Step 1: Set up the Ratio
The first step in finding what percentage 15 is of 75 is to set up a ratio between the two numbers. We can express this ratio as:
15/75
Step 2: Simplify the Ratio
To simplify the ratio, we can divide both the numerator and denominator by their greatest common divisor. In this case, the greatest common divisor of 15 and 75 is 15. Dividing both by 15, we get:
1/5
Step 3: Convert Ratio to Percentage
To convert the simplified ratio into a percentage, we need to multiply it by 100. Since a percentage represents a value out of 100, multiplying the ratio by 100 will give us the desired result. Therefore, we have:
(1/5) * 100 = 20%
Step 4: The Answer
After performing the necessary calculations, we find that 15 is 20 percent of 75. In other words, 15 is one-fifth of 75, which is equivalent to 20 percent.
Why Percentages Matter
Percentages are incredibly useful in various real-life situations. They allow us to easily compare values and understand proportions. For instance, when shopping, we often encounter discounts expressed as percentages. Understanding percentages can help us determine the final price of an item after applying a discount or calculate the amount of money saved. Percentages also play a significant role in areas such as finance, statistics, and scientific research.
Real-World Example
Let's consider a real-world example to further illustrate the concept. Imagine you went to a restaurant with a group of friends and the total bill amounted to $75. If you want to calculate how much each person should contribute if you decide to split the bill equally, finding out what percentage each person owes is essential. By using the steps mentioned earlier, you can determine that each person should pay 20% of the total bill, which amounts to $15.
Conclusion
Understanding percentages is fundamental for many aspects of everyday life. By following a few simple steps, we can easily calculate what percentage one number is of another. In our case, we found that 15 is 20 percent of 75. So, the next time you come across a similar problem, remember to set up a ratio, simplify it, convert it to a percentage, and voila! You'll have your answer.
Introduction
In mathematics, understanding the concept of percentages is crucial. Percentages are used to express a proportion or a part of a whole in terms of a hundred. By determining what percent one number is of another, we can gain valuable insights into the relationship between the two numbers. In this explanation, we will explore how to calculate the percentage value of 15 in relation to 75.
Definition
To understand what it means for a number to be a certain percent of another number, we need to grasp the concept of proportion. When we say that 15 is a certain percent of 75, we are essentially saying that 15 is a part or fraction of 75, expressed as a percentage. In other words, we want to find out what portion of 75 is represented by 15.
Calculation
The process to determine the percent value of 15 in relation to 75 involves a series of steps. We will start by using a mathematical formula specifically designed for finding percentages.
Formula
The formula to find the percent value is:
Percentage = (Part/Whole) * 100
In this case, our part is 15 and our whole is 75. Now, let's substitute these values into the formula.
Substituting values
Percentage = (15/75) * 100
Multiplication
To calculate the numerator of the formula, we multiply 15 by 100.
Percentage = (15 * 100) / 75
Division
Finally, to calculate the final percentage value, we divide the result of the multiplication by 75.
Percentage = 1500 / 75
Result
The result of the calculation is:
Percentage = 20
Explanation
The calculated percentage indicates that 15 is 20% of 75. This means that 15 represents one-fifth or 20 parts out of a hundred parts of 75. It can also be interpreted as 15 being a fraction of 75, where the fraction is 1/5 or 0.20. In practical terms, this could represent a situation where 15 items out of a total of 75 items are of a particular type or have a specific characteristic.
Conclusion
In conclusion, we have explored the concept of determining what percent one number is of another. By following the step-by-step process outlined above, we found that 15 is 20% of 75. Understanding percentages and their calculations allows us to better analyze proportions and make informed decisions in various fields, such as finance, statistics, and everyday life.
When calculating the percentage of one number in relation to another, we can use a simple formula. In this case, we are trying to find out what percentage 15 is of 75.
To calculate this, we can follow these steps:
- Divide the number we want to find the percentage of (15) by the total number (75).
- Multiply the result by 100 to convert it into a percentage.
Let's apply these steps:
- 15 ÷ 75 = 0.2
- 0.2 × 100 = 20%
Therefore, 15 is 20% of 75.
