This article will guide you through the steps, providing both the calculation and explanations to build your understanding of percentages.

Understanding Percentages

A percentage represents a fraction of 100. For example, 50% means 50 out of 100, or 50/100, which simplifies to 1/2. To find what percent 4 is of 12, we need to determine the fraction 4/12 and then convert it into a percentage.

Calculating the Percentage

Here's how to calculate what percent 4 is of 12:

1. Form a Fraction: Express the problem as a fraction: 4/12. This represents 4 out of 12.

2. Simplify the Fraction (Optional): This step isn't strictly necessary but makes the calculation easier. Both 4 and 12 are divisible by 4, simplifying the fraction to 1/3.

3. Convert to a Decimal: Divide the numerator (top number) by the denominator (bottom number): 1 ÷ 3 = 0.333... (this is a repeating decimal).

4. Convert to a Percentage: Multiply the decimal by 100: 0.333... × 100 ≈ 33.33%.

Therefore, 4 is approximately 33.33% of 12.

Alternative Method: Using Proportions

You can also solve this using proportions:

• Set up a proportion: x/100 = 4/12 (where 'x' represents the percentage we're trying to find).

• Cross-multiply: 12x = 400

• Solve for x: x = 400/12 ≈ 33.33%

This method provides the same result, demonstrating a different approach to the problem.
