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?
How many marbles does Kyle have? ** Kyle has a third of Fabian's number of marbles, so he has 15 / 3 = <<15/3=5>>5 marbles.
How many marbles does Miles have? ** Miles has a fifth of Fabian's number of marbles, so he has 15 / 5 = <<15/5=3>>3 marbles.
How many marbles do Kyle and Miles have together? ** Miles and Kyle together have 5 + 3 = <<5+3=8>>8 marbles.
