Prove (A is a union of B)/(A is an intersection of B)=(A/B) is a union of (B/A)

2. Relevant equations

3. The attempt at a solution

Could someone first help me translate all of this into plain English. I don't really understand what I need to prove. Would I start off with the contrapositive? Is the contrapositive "If (A/B) is not the union of (B/A), then A is not the union of B/(A is not the intersection of B) and it is not equal to the antecedent"? Could someone please show me where to go from here?

Thank you very much
