Finding what percentage one number represents of another is a common calculation in math and everyday life. This article will guide you through calculating what percentage 32 is of 80, explaining the process step-by-step so you can easily solve similar problems. Understanding this concept is crucial for various applications, from calculating discounts to analyzing data.

Understanding Percentage Calculations

A percentage represents a fraction of 100. When we say "x% of y," we mean (x/100) * y. In our case, we want to find the percentage that 32 represents of 80.

Calculating the Percentage: Step-by-Step

Here's how to calculate what percentage 32 is of 80:

Step 1: Set up the equation.

We can represent the problem as follows:

x/100 * 80 = 32

Where 'x' represents the unknown percentage we're trying to find.

Step 2: Simplify the equation.

To solve for 'x', we first simplify the equation:

80x/100 = 32

Step 3: Isolate 'x'.

Next, we need to isolate 'x' by multiplying both sides of the equation by 100 and then dividing by 80:

x = (32 * 100) / 80

Step 4: Calculate the result.

Now, perform the calculation:

x = 3200 / 80

x = 40

Step 5: State the answer.

Therefore, 32 is 40% of 80.

Alternative Method: Using a Proportion

Another way to approach this problem is by using proportions:

32/80 = x/100

Cross-multiply:

80x = 3200

Solve for x:

x = 3200/80 = 40

Again, this confirms that 32 is 40% of 80.

Practical Applications

Understanding percentage calculations is valuable in many real-world situations:

• Discounts: If a $80 item is on sale for $32 off, you've received a 40% discount.
• Grade Calculations: If you scored 32 out of 80 on a test, your percentage score is 40%.
• Data Analysis: Percentage calculations are essential for interpreting data in various fields like finance, statistics, and science.

Conclusion

Calculating what percentage 32 is of 80 is straightforward. By using either the equation method or the proportion method, we find that 32 represents 40% of 80. Mastering this type of calculation is a valuable skill with broad applications in many areas of life.
