A) 15 red marbles for every 6 blue marbles

To get from 5 to 15, we multiply by 3. To get from 2 to 6, we also multiply by 3. So the ratio 15 red marbles to 6 blue marbles is equivalent to the given ratio.

B) 30 red marbles for every 12 blue marbles

To get from 5 to 30, we multiply by 6. To get from 2 to 12, we multiply by 6 as well. So the ratio 30 red marbles to 12 blue marbles is also equivalent to the given ratio.

C) 9 red marbles for every 6 blue marbles

To get from 5 to 9, we multiply by 9/5. To get from 2 to 6, we multiply by 3. So the ratio 9 red marbles to 6 blue marbles is equivalent to the given ratio.

D) 25 red marbles for every 10 blue marbles

To get from 5 to 25, we multiply by 5. To get from 2 to 10, we multiply by 5. So the ratio 25 red marbles to 10 blue marbles is also equivalent to the given ratio.

So the correct answers are A, B, and D.
