Three friends Wolfgang, Ludo, and Michael, went to Walmart and bought marbles. Wolfgang bought 16 marbles, Ludo bought 1/4 times more marbles than Wolfgang, and Michael bought 2/3 times as many marbles as the number of marbles both Wolfgang and Ludo bought. If they combined their marbles and decided to share them equally, how many marbles did each get? Think carefully first, then make a decision:
Ludo bought 1 / 4 more marbles than Wolfgang, which is 1 / 4 * 16 marbles = 4 marbles. The total number of marbles that Ludo bought is 16 marbles + 4 marbles = 20 marbles. Wolfgang and Ludo purchased a total of 20 marbles + 16 marbles = 36 marbles. If Michael bought 2 / 3 times the total number of marbles bought by Wolfgang and Ludo, he bought 2 / 3 * 36 marbles = 24 marbles. The three friends purchased a total of 24 marbles + 36 marbles = 60 marbles. When they shared the marbles equally, each got 60 marbles / 3 people = 20 marbles / person. So, the answer is 20.
