If you have 54 blue marbles and 99 yellow marbles, what is the greatest number of identical marble bags that can be made without any marbles leftover?
a) 6
b) 9
c) 12
d) 18

The answer should be D) 18 because both 54 and 99 can divide by 3 and when you divide 54 by 3, you get 18 and that's the most bags you can have while still having both colors. Hope I could help.
