1. The problem is to add the fractions $\frac{2}{9}$ and $\frac{8}{9}$. 2. When adding fractions with the same denominator, you add the numerators and keep the denominator the same. The formula is: $$\frac{a}{c} + \frac{b}{c} = \frac{a+b}{c}$$ 3. Here, both fractions have the denominator 9, so we add the numerators: $$2 + 8 = 10$$ 4. Therefore, $$\frac{2}{9} + \frac{8}{9} = \frac{10}{9}$$ 5. The fraction $\frac{10}{9}$ is an improper fraction and can also be written as the mixed number $1 \frac{1}{9}$. Final answer: $\frac{10}{9}$ or $1 \frac{1}{9}$.
