A fraction bar diagram is a visual tool used to represent fractions, helping to better understand the concept of parts of a whole. Each fraction is shown as a part of a divided bar, with the entire bar representing "1" (the whole). The bar is divided into equal parts, and each shaded part represents the numerator of the fraction.

Here’s how to work with a fraction bar diagram step-by-step:

### Step 1: Draw a bar
- Start by drawing a horizontal rectangle, which will represent the whole number 1.

### Step 2: Divide the bar into equal parts
- Divide the bar into equal sections based on the denominator of the fraction. For example:
  - For a fraction like **1/4**, divide the bar into 4 equal parts.
  - For **3/5**, divide the bar into 5 equal parts.

### Step 3: Shade the correct number of parts
- The number of shaded parts corresponds to the numerator. For example:
  - For **1/4**, shade one of the four sections.
  - For **3/5**, shade three of the five sections.

### Example 1: Representing 3/4
1. Draw a bar and divide it into 4 equal parts (since the denominator is 4).
2. Shade 3 out of the 4 parts to represent the fraction **3/4**.

### Example 2: Representing 2/3
1. Draw a bar and divide it into 3 equal parts.
2. Shade 2 out of the 3 parts to represent the fraction **2/3**.

The fraction bar diagram gives a clear visual representation of fractions and can also be used for comparing fractions or understanding addition and subtraction of fractions.
