To add these two fractions, we need to find a common denominator. The least common multiple of 9 and 15 is 45.

Converting 8/9 to have a denominator of 45:

8/9 = (85) / (95) = 40/45

Converting 4/15 to have a denominator of 45:

4/15 = (43) / (153) = 12/45

Now we can add the fractions:

40/45 + 12/45 = 52/45

Therefore, 8/9 + 4/15 = 52/45.
