Answer:
5:17
Step-by-step explanation:
there are 17 total marbles and 5 that are green. The part is 5 and the whole is 17.
Let
be the two numbers. We have two pieces of information:
(the difference between the two numbers is 2)
(their product is 224)
From the first equation, we can deduce 
If we plug this expression in the second equation, we have

If you solve this equation with the usual quadratic formula you get the solutions

So, you have the following couple of solutions, recalling that x is 2 more than y:
