Answer 1

For your professor's, you gotta use the table , ululasy found at the back of your textbook or chapter, in the appendix, etc. I don't recommend using the table because it only works under certain uniform situations. The table's answer will also not be the exact correct answer; and the error will be bigger in bigger problems. Cheers.

Answer 2

2/3P1 = 1/2P2
