Fabian has three times more marbles than Kyle and five times more than Miles. If Fabian has 15 marbles, how many marbles do Kyle and Miles have together? Let's be accurate as possible.
User
Kyle has a third of Fabian's number of marbles, so he has 15 / 3 = 5 marbles. Miles has a fifth of Fabian's number of marbles, so he has 15 / 5 = 3 marbles. Miles and Kyle together have 5 + 3 = 8 marbles.
The answer: 8.
