Answer: Green Marbles: 25

Yellow Marbles: 30

Red Marbles: 15

Blue Marbles: 40

Explanation:

We know that there are 25 marbles.

We also know that there are 5 green marbles to 6 yellow marbles.

Do this:

5/6 = 25/y

5 y/6 = 25 y/y

5 y = 6 * 25

5 y = 150

y = 30

So, there are 30 yellow marbles.

If there is 1 red marble for every 2 yellow marbles, then there must be 15 red marbles.

Lastly, if the total number of red marbles and green marbles is equal to the number of blue marbles, the number of blue marbles is 15 + 25 = 40

There is 25 green marbles, 30 yellow marbles, 15 red marbles, and 40 blue marbles.

I hope this helps you! :)

Answer:

Green = 25 Yellow = 30 Red = 15 Blue = 40

If there are 25 there should be five groups so there are 5 groups and 6 yellow for each so 6 x 5 = 30 so 30 yellow

if there are 30 yellow and 1 read marble for each 2 there are 15 bcuz 30 divided by 2 = 15

now if you add the red and green you get 40.

Hopefully thats right!
