-->800/64*1296/36.
-->100/8*216/6.
-->25/2*36.

---> 800/64= (2^3*10^2)/(2^3 * 2^3).
---> 1296/36=(6^2*6^2)/(6^2),
--> cancel the similar terms and next we get.
---> (10^2)*(6^2)/(2^3) = 3600/8 = 450.

800/64 *1296/36.
(2^3*10^2/2^6) * (6^4/6^2).
By solving like this we get easily the answer.
10^2*6^2/2^3.
3600/8=450.

Please give a another example.

--> (8*100)/(8*8) = 12.5.

--> (36*36)/36 = 36.

--> 36*12.5 = 450.
