Ok so this is the first time I have ever seen this and it is very confusing. I have an assignment that I need to complete by Sunday night but I am having no luck in this question. Could anyone explain how I am to finish this in a easy to understand way?

Here is the question:

Assume f1(n) is O(g1(n)) and f2(n) is O(g2(n)), show that f1(n)/f2(n) is NOT O(g1(n) / g2(n)).

Of course all the 1's and 2's are supposed to be subscripts but I do not know how to do that on this form. Thank you for any and all help. Also I am to start with the definition of big-O.
