Introduction

In this article, we will explore the mathematical concept of finding 75% of a given number, specifically 30. Understanding how to calculate percentages is essential in various real-life scenarios, such as shopping discounts, calculating taxes, or analyzing data trends. By breaking down the process step-by-step, we will explain how to determine what 75% of 30 is.

Understanding Percentages

Before delving into the calculation, let's ensure we have a clear understanding of percentages. A percentage represents a fraction of 100, with the symbol % denoting per cent, meaning out of a hundred. Therefore, when we calculate a certain percentage of a number, we find that proportion out of 100.

Breaking Down the Calculation

Calculating 75% of 30 involves multiplying 30 by the decimal equivalent of 75%. To convert a percentage to a decimal, divide it by 100. In this case, 75 divided by 100 equals 0.75. Thus, to find 75% of 30, we multiply 30 by 0.75.

Multiplying 30 by 0.75

To calculate the product of 30 and 0.75, we multiply them together. When we multiply 30 by 0.75, we get the result: 22.5. Therefore, 75% of 30 is equal to 22.5.

Visual Representation

Another way to comprehend this calculation is through a visual representation. Imagine a whole representing 100%, which in this case is 30. If we divide this whole into four equal parts, each part would represent 25%. Since we are looking for 75%, we take three of these parts. Each part would be 7.5, and adding them together gives us a total of 22.5.

Using the Percentage Formula

Alternatively, we can use the percentage formula to find 75% of 30. The formula states that part = (percentage / 100) × whole. Substituting the given values, we have part = (75 / 100) × 30. Simplifying this equation yields part = 0.75 × 30, which results in the same value of 22.5.

Practical Examples

Understanding how to calculate percentages is essential for practical applications. For instance, if you are shopping and there is a 75% discount on an item that costs $30, you can determine the discounted price by multiplying 30 by 0.75. The discounted price would be $22.50.

Calculating 75% of Another Number

Now that we have grasped the concept of finding 75% of 30, we can apply the same approach to any other number. Simply substitute the desired number in place of 30 and follow the steps outlined above. For example, to find 75% of 50, we would multiply 50 by 0.75, resulting in 37.5.

Rounding the Result

In some cases, it may be necessary to round the result when dealing with percentages. If precision is not crucial, rounding to a specific decimal point or whole number might be appropriate. However, it is important to consider the context and requirements of the calculation before deciding whether rounding is necessary.

Conclusion

Calculating percentages is a fundamental skill that finds applications in numerous real-life scenarios. In this article, we focused on finding 75% of 30 by multiplying 30 by the decimal equivalent of 75%, which is 0.75. The result of this calculation is 22.5. By understanding and applying these principles, you can confidently calculate percentages and solve various mathematical problems.
