20% of 50 marbles is 1 fifth of the marbles in the bag. so 50 marbles divided by 5 =10 blue marbles
minus one red marble plus one blue marble
There has to be 12 marbles in the group. If 4 are red that is 1/3 of 12 and if 3 are blue that is 1/4 of 12. The rest can be any color. That is how you explain how four red marbles can make up 1/3 of a group of marbles and three blue marbles make up 1/4 of the same group :)
10 Green marbles, 13 Blue marbles.
