To simplify the expression 6/7c - 5/9d - 1/2c + 1/3d, we can combine like terms.
First, let's combine the terms with "c": 6/7c - 1/2c = (12/14)c - (7/14)c = (12 - 7)/14c = 5/14c.
Next, let's combine the terms with "d": -5/9d + 1/3d = (-15/27)d + (9/27)d = (-15 + 9)/27d = -6/27d = -2/9d.
Therefore, the simplified expression is 5/14c - 2/9d.
