1. **State the problem:** Simplify the expression $$\frac{(3xy^{-2})^{-2}}{3x^{-2}y}$$.
2. **Recall exponent rules:**
- Power of a power: $$(a^m)^n = a^{mn}$$
- Negative exponent: $$a^{-m} = \frac{1}{a^m}$$
- Product of powers: $$a^m \cdot a^n = a^{m+n}$$
- Quotient of powers: $$\frac{a^m}{a^n} = a^{m-n}$$
3. **Simplify numerator:**
$$(3xy^{-2})^{-2} = 3^{-2} \cdot x^{-2} \cdot (y^{-2})^{-2} = 3^{-2} x^{-2} y^{4}$$
4. **Rewrite the expression:**
$$\frac{3^{-2} x^{-2} y^{4}}{3 x^{-2} y}$$
5. **Divide coefficients and variables:**
$$= 3^{-2 - 1} \cdot x^{-2 - (-2)} \cdot y^{4 - 1}$$
6. **Simplify exponents:**
$$= 3^{-3} \cdot x^{0} \cdot y^{3}$$
7. **Simplify further:**
Since $$x^{0} = 1$$,
$$= \frac{y^{3}}{3^{3}} = \frac{y^{3}}{27}$$
**Final answer:** $$\frac{y^{3}}{27}$$
