We are not here just to answer your homework for you.

Any ratio is going to be the first thing divided by the second. You have a price to book -- same thing. First thing divided by the second. And obviously, you need the price to do this.

And of course, you need the answer to (a) before you can do (b). But you need to make an attempt to answer that question, and then we can help you from there.
