Answer:
Seeing as he has a bag full of 12 red marbles, 20 green marbles, and 17 blue marble I would say 0/49 from what I read there is no purple in the bag at all
But I got 49 by adding all the marbles together I think that is the answer but i'm not totally sure.
1/4. i believe but im not too sure
The answer is 125 because you have to find the unit rate of each number. When you divide 60,000 by 30, you should get 2000. When you divide 75,000 by 40, you should get 1875. Then, you subtract the two answers and get 125.
