what do you have so far?

yes, that is the right idea.  It is not a "great example" because you are assuming it takes the same amount of time to finish the homework for each class. (math might take longer than English)

Of course, you could say:   Lisa spends the same amount of time doing homework for each class.  

That will make it clearer.

Do you know how I can solve this as a fraction.
