Fractions and percentages are two ways of expressing parts of a whole. Understanding how to convert between them is a crucial skill in many areas, from everyday calculations to more advanced mathematics. This article will guide you through converting the fraction 2/9 into a percentage, explaining the process clearly and concisely.

Understanding the Conversion Process

To convert a fraction to a percentage, you need to understand that a percentage is simply a fraction with a denominator of 100. Therefore, the goal is to transform our fraction, 2/9, into an equivalent fraction with 100 as the denominator.

Step 1: Divide the Numerator by the Denominator

The first step in converting 2/9 to a percentage is to divide the numerator (the top number, 2) by the denominator (the bottom number, 9).

2 ÷ 9 = 0.222...

This gives us a decimal value of approximately 0.222. The three dots indicate that the decimal continues infinitely. For practical purposes, we'll usually round to a certain number of decimal places.

Step 2: Multiply by 100

The next step is to multiply the decimal value obtained in Step 1 by 100. This converts the decimal to a percentage.

0.222... × 100 = 22.22% (approximately)

We've rounded the result to two decimal places for simplicity.

2/9 as a Percentage: The Final Answer

Therefore, 2/9 as a percentage is approximately 22.22%. Remember that this is an approximation because the decimal value of 2/9 is recurring.

Alternative Method: Using Proportions

Another approach to solving this problem involves setting up a proportion:

2/9 = x/100

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

9x = 200

x = 200/9

x ≈ 22.22

This confirms our previous calculation.

Frequently Asked Questions (FAQs)
