anonymous · Answer

You can easily find how many sets of  5 red marbles there are. And you know that for every set of 5 red marbles you have a set  of green marbles, so go from there

is there a certtain way to set up a math problem to work this out

anonymous · Answer

You have 45 red marbles, 45/5 = 9, so that means you have 9 sets of 5 red marbles, yep?

anonymous · Answer

And for every 5 red you have 7 green ones, so the total number of green marbles is just 7x9

so 7x9 would be the answer
