Understanding percentages is crucial in many areas, from calculating discounts and taxes to analyzing data and understanding statistics. This seemingly simple calculation can be applied to a wide range of real-world scenarios, such as determining the completion rate of a project or calculating a student's score on a test. We'll break down the process into easy-to-follow steps.

Understanding the Problem:

The question "What percent of 80 is 32?" asks us to find the percentage that 32 represents when considered as a part of the whole, which is 80. We need to determine what fraction 32 is of 80, and then express that fraction as a percentage.

Method 1: Using a Proportion

This method utilizes the concept of ratios and proportions. We can set up a proportion to solve this problem:

• Part/Whole = Percentage/100

In our case:

• 32/80 = x/100

To solve for 'x' (the percentage), we cross-multiply:

• 32 * 100 = 80 * x
• 3200 = 80x

Now, divide both sides by 80:

• x = 3200 / 80
• x = 40

Therefore, 32 is 40% of 80.

Method 2: Using Decimal Conversion

This method involves converting the fraction into a decimal and then multiplying by 100 to express it as a percentage.

1. Form the Fraction: Express 32 as a fraction of 80: 32/80

2. Simplify the Fraction (Optional): Simplifying the fraction can make the calculation easier. In this case, both the numerator and denominator are divisible by 16: 32/80 simplifies to 2/5

3. Convert to Decimal: Divide the numerator by the denominator: 2 ÷ 5 = 0.4

4. Convert to Percentage: Multiply the decimal by 100: 0.4 * 100 = 40%

Therefore, 32 is 40% of 80.

Method 3: Using a Calculator

Most calculators have a percentage function. Simply divide 32 by 80 and then multiply the result by 100. The calculation would look like this: (32 ÷ 80) x 100 = 40%

Conclusion:

Using any of these methods, we've definitively shown that 32 is 40% of 80. Understanding these calculation methods will empower you to solve similar percentage problems with confidence. Remember, the key is to understand the relationship between the part, the whole, and the percentage. Practice these methods, and you'll quickly become proficient in percentage calculations.
