Completely lost - potential dividers etc.

i missed a lesson on monday due to a field trip and they did about potential dividers, emf, and internal resistance. I've tried reading up in textbooks and on the internet but nothing seems to be going in. I understand what emf/internal resistance is but when i tried to do some homework questions i didnt get it at all. Also i dont really understand what potential dividers do. Any advice?

Thanks
(i spoke to me teacher but she said just look throught the textbook)
