2/3+5/9

To add fractions, the first step is to find a common denominator. In this case, the least common multiple (LCM) of 3 and 9 is 9.

Next, we need to convert the fractions so they have the same denominator.

For 2/3, we need to multiply both the numerator and denominator by 3:

(2/3) x (3/3) = 6/9.

For 5/9, we don't need to change anything because the denominator is already 9.

Now that both fractions have a common denominator, we can add them together:

6/9 + 5/9 = 11/9.

Therefore, the sum of 2/3 and 5/9 is 11/9.
