51/78 Would the correct answer be 3/4

which I divided by 17

First divide both sides by three and see what we get:
17/26

One of those terms is already a prime number, so that is as far as you can go.

51/68 would be 3/4, but 51/78 is not.
Nope. 78 isn't evenly divisible by 17.

Both 51 and 78 are divisible by 3.

51/78 = 17/26
