To simplify the expression, we can combine like terms.
The like terms in the expression are the terms with the same variables raised to the same powers: 6/7c and -1/2c can be combined, and -5/9d and 1/3d can also be combined.
6/7c - 1/2c = (12/14)c - (7/14)c = 5/14c
-5/9d + 1/3d = (-15/27)d + (9/27)d = -6/27d = -2/9d
Therefore, the simplified expression is 5/14c - 2/9d.
So, the correct answer is C.
Simplify 6/7c - 5/9d - 1/2c + 1/3d
A. 5/9c - 4/12d = 5/9c - 1/3d
B. 5/14c + 2/9d
C. 5/14c - 2/9d
D. 5/9c + 4/12d = 5/9c + 1/3d
