please help!

On the number line above, points J, K, L, and M are integers, and JK:KL:KM = 2:1:3. What is the value of KM?

J          K     L               M

     2        1          3               | \(\times\frac{24}{6}\)

     8        4         12

                    16

The value of KM is 16.  (G)

That is what I THOUGHT the answer MIGHT be.....but the question states   KM  is  '3'   in the ratio 2:1:3   

          I believe it should state LM is   '3' in the   2:1:3      which it looks as though your answer assumed (o/w the answers would not be integers)
