Answer:
Explanation:
If 10 marbles are white, then there are 15 marbles that are not white.
If 1/4 of the marbles are red, then there are 25 x 1/4 = 6.25, which we can round up to 7 red marbles.
If 1/2 of the marbles are blue, then there are 25 x 1/2 = 12.5, which we can round down to 12 blue marbles.
The remaining marbles must be green: 25 - 10 - 7 - 12 = 25 - 29 = -4. This doesn't make sense,
