new accounting homework

I need just simple answers. Not too long. It is just a discussion. Two questions:

1.You have been introduced to many types of ratios this term. Discuss, in your own words, some of the benefits that ratios can provide. Also discuss some of the limitations. Use an example to demonstrate a benefit, and another to explain a limitation.

2.Discuss the triple bottom line and corporate social responsibility. How can a company be more profitable by following these? Looking for at least one example per post (personal or researched). Remember good examples get rewarded
