To convert a fraction to a percentage, we need to understand that a percentage is simply a fraction with a denominator of 100. Therefore, our goal is to transform the fraction 2/7 into an equivalent fraction with 100 as the denominator.

Step-by-Step Calculation: Converting 2/7 to a Percentage

1. Divide the numerator by the denominator: The first step is to perform the division 2 ÷ 7. This will give you a decimal value. Using a calculator, you'll find that 2 ÷ 7 ≈ 0.2857.

2. Multiply the decimal by 100: To convert the decimal to a percentage, we multiply the result by 100. So, 0.2857 x 100 = 28.57.

3. Add the percentage symbol: Finally, add the percentage symbol (%) to indicate that the result is a percentage.

Therefore, 2/7 as a percent is approximately 28.57%.

Understanding the Approximation

It's important to note that the answer is an approximation. The decimal representation of 2/7 is a non-terminating decimal (it goes on forever without repeating). We've rounded the decimal to two decimal places for simplicity and practicality. For most purposes, 28.57% is a sufficiently accurate representation.
