Introduction
Calculating percentages is a fundamental skill that we use in our daily lives. Whether we are shopping, budgeting, or analyzing data, percentages play a crucial role. In this article, we will discuss how to calculate “32 is what percent of 80” in relaxed English language. We will provide step-by-step instructions and examples to help you understand the concept of percentages and how to apply it to this problem.
What is a Percentage?
A percentage is a way of expressing a number as a fraction of 100. For example, 50% is the same as 50/100 or 0.5. Percentages are often used to represent proportions or ratios, such as the percentage of students who passed an exam or the percentage of a budget that is allocated to a specific department.
Step-by-Step Calculation
To calculate “32 is what percent of 80,” we can use the following formula:
Part/Whole x 100 = Percentage
In this case, the part is 32, the whole is 80, and the percentage is unknown. We can plug these values into the formula and solve for the percentage:
32/80 x 100 = 40%
Therefore, 32 is 40% of 80.
Examples
Let’s look at some examples to further illustrate how to calculate percentages.
Example 1: What is 25% of 80?
To solve this problem, we can use the same formula:
Part/Whole x 100 = Percentage
We know that the percentage is 25%, the whole is 80, and the part is unknown. We can plug these values into the formula and solve for the part:
X/80 x 100 = 25%
X = 20
Therefore, 25% of 80 is 20.
Example 2: If 60% of a class passed an exam, and there were 40 students in the class, how many students passed?
To solve this problem, we can use the formula:
Percentage/100 x Whole = Part
We know that the percentage is 60%, the whole is 40, and the part is unknown. We can plug these values into the formula and solve for the part:
60/100 x 40 = 24
Therefore, 24 students passed the exam.
Tips and Tricks
Here are some tips and tricks to help you calculate percentages more easily:
- When calculating percentages, always remember to divide the part by the whole before multiplying by 100.
- If you are given the percentage and the whole, you can use the formula Percentage/100 x Whole = Part to solve for the part.
- If you are given the part and the whole, you can use the formula Part/Whole x 100 = Percentage to solve for the percentage.
- When working with decimals, remember to move the decimal point two places to the right to convert to a percentage.
Conclusion
Calculating percentages is a useful skill that can be applied to a variety of real-world situations. By understanding the formula and following the steps outlined in this article, you can easily calculate “32 is what percent of 80” and other percentage problems.
