### Algebraic Expressions and Fractions

In the following exercises, you will perform operations on algebraic fractions and express answers in simplified form.

**Exercise 2**

Perform the division operation on the given algebraic expressions:
\[
\frac{13x^2}{20y^2} \div \frac{39x^2}{5y} \div \frac{2y^3}{26x^5y}
\]

**Exercise 3**

Simplify the expression by dividing the polynomial fractions:
\[
\frac{2a^2 - 11a + 12}{27 - 18a} \div \frac{a^3 + 4a^2}{6a^3 - 96a}
\]

**Exercise 4**

Solve the division of the given expressions:
\[
\frac{x^3 - 64}{x^3 + 64} \div \frac{x^2 - 16}{x^2 - 4x + 16}
\]

**Exercise 5**

Divide and simplify the polynomial expressions:
\[
\frac{8y^3 - 27}{64y^3 - 1} \div \frac{4y^2 - 9}{16y^2 + 4y + 1}
\]

**Exercise 6**

Simplify the expression involving multiplication and division of fractions:
\[
\frac{a^3 + b^3}{a^2 + 3ab + 2b^2} \cdot \frac{3a - 6b}{3a^2 - 3ab + 3b^2} \div \frac{a^2 - 4b^2}{a + 2b}
\]

### Instructions

1. **Identify Common Factors**: Before performing operations, factorize the expressions to identify any common factors.
2. **Apply Operations**: Use appropriate arithmetic operations (multiplication, division) as indicated by the problems.
3. **Simplify**: Obtain the simplified fraction or algebraic expression by canceling out common factors.

These exercises will help you deepen your understanding of polynomial fraction operations and enhance your simplification skills.
