### Complete the Solution

Solve the expression step by step. The provided image contains an equation involving fractions and algebraic expressions.

#### Initial Expression:
\[
\frac{6}{3v} - \frac{1}{7v^2} = \frac{6}{3v} \cdot \frac{7v}{7v} - \frac{1}{7v^2} \cdot \frac{3}{3}
\]

This is the starting point for solving the expression. There are a few blank boxes that need to be completed to find the full solution.

#### Step-by-Step Solution:

1. **Multiply each term by a form of one to create common denominators:**
   \[
   \frac{6}{3v} \cdot \frac{7v}{7v} - \frac{1}{7v^2} \cdot \frac{3}{3}
   \]

2. **Perform the multiplications:**
   \[
   \frac{42v}{21v^2} - \frac{3}{21v^2}
   \]
   The numerator for the first term becomes \(42v\), since \(6 \times 7v = 42v\). For the second term, the numerator becomes \(3\), since \(1 \times 3 = 3\). The common denominator is \(21v^2\).

3. **Combine the fractions:**
   \[
   \frac{42v - 3}{21v^2}
   \]

Each step fills in the corresponding blank boxes in the image.

#### Diagram Explanation:

- The first line shows the initial expression.
- Subsequent lines guide through filling in the blank boxes for each calculation step.
- Fraction multiplications and common denominator formation are demonstrated with intermediate simplifications.

This process demonstrates how to manipulate algebraic fractions to work towards a common denominator, enabling combination into a single simplified fraction. Such exercises are fundamental in algebra learning.
