Griffin, good job on your problem. My answers mach yours. Your formatting is a little hard to follow. I would try to separate out your problems a little more. Also for your last problem your two pictures are in the wrong order. Make sure you put the units on to your numerical values. Lastly for the first step I would suggest putting a few more steps in, just to clarify what you are doing. But over all good work!
Great Job Griffin. They only thing I would suggest is just to not forget the units and for part be add in the actual equation you are using ( E=hu). Other than that we can the same values. Good work!
