In a bag of marbles, [unparseable or potentially dangerous latex formula] of the marbles are blue and the rest are red. If the number of red marbles is doubled and the number of blue marbles stays the same, what fraction of the marbles will be red?

Hypothetically, there should be three blue marbles for every two red marbles. Should the number of red marbles double, it'll be three blue marbles for every four red marbles. Thus, the fraction, which I'm betting on as the answer, of the marbles that are red would be:
[unparseable or potentially dangerous latex formula]
Now I know the stakes, and I'm willing to show what I gots. I will see you all at state for the first and final time, so let's end the year with a bang! :)
