Kai Ling, Sam and Marie shared a bag of candies. Kai Ling received 2/5 of the candies, Sam received 2/3 as many candies as Kai Ling. Marie received 65 candies. How many more candies did Kai Ling receive than Sam?

Sam had (2/3)*(2/5) = 4/15 of the candies
Kai Ling had 2/5 = 6/15.
That leaves 5/15 = 1/3 for Marie, who has 65. Therefore the total number is 65*3 = 195.
Kai Ling has 78
Sam has 52
Marie has 65.
(Kai Ling #)  (Sam #) = 26
