**Understanding Fraction to Percentage Conversion**

Fractions and percentages are two common ways to express parts of a whole. Converting a fraction to a percentage is a way of expressing that fraction as a portion of 100. In the case of 20/30, we want to determine what percentage of a whole it represents.

**Step-by-Step Conversion**

Let’s break down the process of converting 20/30 to a percentage:

**Step 1: Simplify the Fraction (if necessary)**

Before converting to a percentage, it’s often helpful to simplify the fraction. In this case, 20/30 can be simplified by dividing both the numerator (20) and denominator (30) by their greatest common divisor, which is 10.

20 ÷ 10 = 2 30 ÷ 10 = 3

So, 20/30 simplifies to 2/3.

**Step 2: Convert to a Decimal**

To convert a fraction to a percentage, we first need to convert it to a decimal. To do this, divide the numerator by the denominator:

2 ÷ 3 ≈ 0.6667 (rounded to four decimal places)

**Step 3: Multiply by 100**

Now that we have a decimal (0.6667), we can convert it to a percentage by multiplying it by 100:

0.6667 × 100 = 66.67%

**Step 4: Round (if necessary)**

In most cases, percentages are rounded to a certain number of decimal places or as a whole number. In this example, we rounded to two decimal places, so 20/30 as a percentage is approximately 66.67%.

**Real-Life Applications**

Understanding how to convert fractions to percentages is a valuable skill in various real-life situations. Here are a few examples:

**Grades and Assessments:**Teachers use percentages to grade assignments, quizzes, and exams.

**Examples**

Let’s explore a couple of examples to reinforce the concept:

**Example 1:** Converting 3/4 to a percentage.
