In the diagram, the rectangle has a width w, a length of 8, and a perimeter of 24 . What is the ratio of its width to its length? Write your answer in the form x:y, where x   and  y are relatively prime positive integers.

The two long sides total 16.  The two short sides total (24 – 16) equals 8 so each one of them is 4. 

 

The ratio of width to length is 4:8 = 1:2.   I'm not sure what relatively prime means, but 1 is not a prime number.
