Finding what percent a number is of another involves a simple percentage calculation. Let's break down how to determine what percent 2 is of 3. This is a fundamental concept in mathematics with applications in many areas, from calculating discounts to understanding statistics.

Understanding Percentages

Before diving into the calculation, let's refresh our understanding of percentages. A percentage is a fraction expressed as a number out of 100. For instance, 50% is the same as 50/100, which simplifies to 1/2. In essence, a percentage shows the proportional relationship between two numbers.

Calculating the Percentage

To find what percent 2 is of 3, we follow these steps:

1. Set up the equation: We can represent the problem as a fraction: 2/3. This fraction shows the relationship between 2 (the part) and 3 (the whole).

2. Convert the fraction to a decimal: Divide the numerator (2) by the denominator (3): 2 ÷ 3 = 0.666... This decimal represents the proportion of 3 that 2 makes up.

3. Convert the decimal to a percentage: Multiply the decimal by 100: 0.666... × 100 ≈ 66.67%.

Therefore, 2 is approximately 66.67% of 3.

Alternative Method: Using Proportions

Another way to solve this problem is by setting up a proportion:

• Let x be the percentage we're looking for.
• The proportion is set up as: x/100 = 2/3

To solve for x, we cross-multiply:

3x = 200

x = 200/3

x ≈ 66.67%

This method confirms our previous calculation.

Practical Applications

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

• Discounts: Calculating sale prices (e.g., 20% off).
• Taxes: Determining the amount of tax on a purchase.
• Tips: Calculating gratuities in restaurants.
• Statistics: Analyzing data and understanding proportions.
• Financial calculations: Working with interest rates, returns on investment, etc.

Conclusion: Mastering Percentages

Knowing how to determine what percent one number is of another is a fundamental skill. By mastering this simple calculation, you can tackle a wide variety of problems involving proportions and percentages, making you more confident in handling everyday mathematical challenges. Remember the simple steps: fraction, decimal, percentage! Now you know that 2 is approximately 66.67% of 3.
