12c/15d
This simplifies to 4c/5d, right? Even though c and d are not necessarily the same value? I just can't remember.

(12 / 15) (c / d)
(4 / 5) (c / d)
4c / 5d is indeed the correct answer.

Yes. Just find the greatest common factor of 12 and 5 which is 3 in this case. So you're left with 4c/5d

You are correct, constants 12 and 15 are divided by same factor 3.
If values of C and D are unkwon: 12 C / 15 D = 4 C / 5 D
If value of C = D then it is just 4 / 5 or 0.8.
If values of C and D are known, then insert them in the equation and calculate answer.

i think 4c/5d is right becase the common number between them is 3

12c/15d =
(12/15) * (c/d) =
(4/5)*(c/d) =
4c/5d

You're absolutely correct.
12/15 reduces, but c/d won't since they are not the same variable and you don't know what they are.

Correct. All you need to do is simplify the numbers.
