Answer 2

To solve the equation 5/9 + 7/15 - 2/3, we need to find a common denominator for the fractions and then combine the terms.

The least common denominator (LCD) for 9, 15, and 3 is 45.

Let's convert each fraction to have a denominator of 45:

5/9 = (5/9) * (5/5) = 25/45 7/15 = (7/15) * (3/3) = 21/45 2/3 = (2/3) * (15/15) = 30/45

Now that all fractions have the same denominator, we can add/subtract them:

25/45 + 21/45 - 30/45

Combining the numerators:

(25 + 21 - 30)/45 = 16/45

Therefore, 5/9 + 7/15 - 2/3 is equal to 16/45.
