1. The problem asks to simplify the expression $$\frac{x}{y}$$ given the context of question 23. 2. Since the user message includes multiple expressions but requests to solve question 23, we focus on the first expression: $$\frac{24}{-6}$$. 3. Use the division rule: dividing a positive number by a negative number results in a negative number. 4. Calculate $$\frac{24}{-6} = -\frac{24}{6}$$. 5. Simplify the fraction by dividing numerator and denominator by 6: $$\frac{\cancel{24}^{4}}{\cancel{6}^{1}} = 4$$ 6. So, $$\frac{24}{-6} = -4$$. 7. Final answer: $$-4$$.
