To add \( \frac{4}{9} \) and \( \frac{2}{3} \), follow these steps:

1. Find a common denominator. The least common denominator (LCD) of 9 and 3 is 9.
2. Convert \( \frac{2}{3} \) to a fraction with a denominator of 9:  
   \( \frac{2}{3} = \frac{2 \times 3}{3 \times 3} = \frac{6}{9} \).
3. Now, add the fractions:  
   \( \frac{4}{9} + \frac{6}{9} = \frac{4 + 6}{9} = \frac{10}{9} \).

So, \( \frac{4}{9} + \frac{2}{3} = \frac{10}{9} \), or as a mixed number, \( 1 \frac{1}{9} \).
