Since it's an assignment using ratios, I would hope they've been teaching these ratios and they should be in your textbook. I don't know if they're wanting you to use specific ones that you have been working on, or whatever you can manage to find.
This is a pretty good site listing many different ratios, with a fair amount of commentary on them:
Investopedia.com: Financial Ratio Tutorial
There's a lot of them here, so if you're supposed to be using a certain set of them, you might have to fish through to find them. (There's some you
can't use simply because you don't have the info. Which leads me to believe they want you to stay fairly simplified.)
If there are certain ones you simply can't understand what they mean, then ask about those specific ones. However, we're not here to do your homework for you so we're not here to try to give you an answer to the problem, but we can help understand any specific ratios.
I wouldn't want to answer the question anyway. These ratios don't always have a lot of meaning without comparing to industry averages. Which is why I hate these kind of assignments -- doing a bunch of math to get a bunch of numbers that you don't even have anything to compare them to.
Just for fun, if you want to compare any with real companies, you can go here:

Near the top left by Get Quote, just type in any company you want. On the left side there's a column and clear down at the bottom are the financial statements. This site has been used at a lot of schools to do these types of assignments on real companies.
