$(16d+5c)/(6cd)$

Firstly, the two minus signs in the middle 'cancel out' to act as a plus sign. So the expression becomes $8/(3c) + 5/(6d)$ .

Then we can find a common denominator by find the LCM (lowest common multiple) of $3c$ and $6d$ , which happens to be $6cd$

Then we can add to get $(8xx2d)/(3cxx2d)+(5xxc)/(6d xx c)$

= $(16d)/(6cd)+(5c)/(6cd)=(16d+5c)/(6cd)$

So the answer is $(16d+5c)/(6cd)$
