bassam has some marbles. one third of them are blue, one half of them are red, and the rest are green. If he has 7 green marbles, how many marbles does he have?
Because 1/3 are blue and 1/2 are red and the rest are green we can calculate that 1/6 of the marbles are green. 1/3 = 2/6 1/2 = 3/6 2/6 + 3/6 = 5/6 which leaves 1/6 green. Since there are 7 green marbles we know there must be 7 x 6 total. The answer is 42 marbles.
