limestone and pentelic marbles
In order for 4 red marbles to be one-third of a group and 3 blue marbles to make up one-fourth of the same group the number has to equal 12.
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 :)
Uranium marbles are glass marbles made with uranium oxide, which gives them a unique fluorescent glow under ultraviolet light. Regular marbles, on the other hand, are made from various materials like glass, clay, or metal, without the use of radioactive materials. Uranium marbles are collectibles due to their distinctive appearance and historical significance.

Set up the problem as: y=number of yellow marbles & 4y=number of blue marbles. 40=y+4y or 40=5y or y=8. Therefore number of blue marbles is 4*8 = 32.
I thought marbles were made of glass. But try Agate, a silica mineral.
