I am supposed to prove the following: Where a,b,c,d are members of a field K (satisfying the field axioms). However, I don't quite understand exactly what this notation signifies; specifically, I don't know what the colon means in this context. Usually it means "such that," but that doesn't really seem to make sense here. So I'm not entirely sure what I'm supposed to prove!

My guess : means divided by.

I finally found where it was defined in our notes. Yeah, you're right. Should have been obvious, but I wasn't entirely sure. Thanks.
