William has a 26-liter glass tank. First, he wants to put some marbles in it, all of the same volume. Then, he wants to fill the
tank with water until it's completely full. If he uses 85 marbles, he will have to add 20.9 liters of of water. What is the volume of each marble?
How much water is necessary if William uses 200 marbles?
I think it would be easier to understand when u see a problem worked out, prime factorization of 18: 18 /\ 6X3 /\ 3X2 so the prime factorization is 2X3X3 hope that was helpful! :D
