A triangle has side lengths 3in, 4in, and 6in. The longest side of a similar triangle is 15in. What is the length of the shortest side of the similar triangle?

The lengths of the sides of a triangle all share the same proportion to the lengths of their corresponding sides of a similar triangle.
If the two unknown lengths are x and y, then: a/3 = b/4 = 15/6
