1. **State the problem:** Solve the equation $$\frac{72}{2h} = 4$$ for $h$. 2. **Understand the equation:** The equation means that 72 divided by $2h$ equals 4. 3. **Isolate $h$:** Multiply both sides by $2h$ to get rid of the denominator: $$72 = 4 \times 2h$$ 4. **Simplify the right side:** $$72 = 8h$$ 5. **Solve for $h$:** Divide both sides by 8: $$h = \frac{72}{8}$$ 6. **Calculate the value:** $$h = 9$$ **Final answer:** $h = 9$
