Red : Blue
2 : 5

As red is 2 parts, and we already know that there are 6 red marbles, we can use this to find that 1 part is 3 marbles (6 divided by 2).

There are 5 parts blue. If 1 part is 3 marbles, then if we multiply that by the amount of parts for blue, we get 15.

Therefore, the bag contains 15 blue marbles.

Answer:

15

Explanation:

there are 2 red marbles for every 5 blue marbles, and we know that there are 6 red marbles total.

2x3=6, so we know that there are 3 sets of 2 red marbles, meaning there is also 3 sets of 5 blue marbles.

So there are 3x5=15 blue marbles in the bag
