1. The problem is to simplify each given expression. 2. Simplification involves reducing expressions to their simplest form by combining like terms, factoring, canceling common factors, or applying algebraic identities. 3. For example, if the expression is a fraction, we look for common factors in numerator and denominator to cancel. 4. Suppose the expression is $$\frac{6x}{9}$$. 5. Factor numerator and denominator: $$\frac{6x}{9} = \frac{\cancel{3} \times 2 x}{\cancel{3} \times 3}$$. 6. Cancel the common factor 3: $$\frac{2x}{3}$$. 7. The simplified form is $$\frac{2x}{3}$$. 8. Always check if further simplification is possible. 9. If you provide specific expressions, I can simplify them step-by-step.
