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! :)
