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?
Kyle has a third of Fabian's number of marbles, so he has 15 / 3 = <T>divide(15, 3)=5.0 marbles.
Miles has a fifth of Fabian's number of marbles, so he has 15 / 5 = <T>divide(15, 5)=3.0 marbles.
Miles and Kyle together have 5 + 3 = <T>add(5, 3)=8 marbles.
