To solve $\frac{1}{3} + \frac{7}{9}$:

1. Find the least common denominator (LCD). The LCD of 3 and 9 is 9.
2. Convert $\frac{1}{3}$ to have a denominator of 9. Multiply both the numerator and denominator by 3: $\frac{1}{3} = \frac{3}{9}$
3. Now, add $\frac{3}{9}$ and $\frac{7}{9}$: $\frac{3}{9} + \frac{7}{9} = \frac{3 + 7}{9} = \frac{10}{9}$

The result is $\frac{10}{9}$, which is an improper fraction. You can also express it as a mixed number: $\frac{10}{9} = 1 \frac{1}{9}$
