%2848x%5E2%29%2F%2864x%5E4%29 = x%2F%2836x%5E2%29.


From the proportion, the product of extreme terms is equal to the product of interior terms


    (48x^2)*(36x^2) = (64x^4)*x


Cancel common factors (16x^4) in both sides to get


    3*36 = 4x

    
Cancel common factor 4 in both side to get


    x = 3*9 = 27.    ANSWER


ANSWER.  x = 27.

Solved.
