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.
