These ratios are not proportional.
Explanation:
If the ratio 8:32 were simplified, it would equal 1:4 because they can both be divided by 8. But since 16 x 4 does not equal 72, they cannot be divided by 4 to make a simplified ratio such as the first example.
Hope I helped, and good luck!

We have been given an equation of hyperbola  . We are asked to find the center of hyperbola.
. We are asked to find the center of hyperbola.  
We know that standard equation of a vertical hyperbola is in form  , where point (h,k) represents center of hyperbola.
, where point (h,k) represents center of hyperbola.
Upon comparing our given equation with standard vertical hyperbola, we can see that the value of h is 6. 
To find the value of k, we need to rewrite our equation as:

Now we can see that value of k is  . Therefore, the vertex of given hyperbola will be at point
. Therefore, the vertex of given hyperbola will be at point  and option D is the correct choice.
 and option D is the correct choice.
