=>Let the number be a ... =>Nine times the number: 9a ... =>Nine time a no. Is 3600 : 9a = 3600... =>9a = 3600 =>a = 3600/9 =>a= 400.. =>So the number is 400.. Hope It helps!!
The way this should be set up is: 

9a = 3600... 

So you must divide '9' on both sides, canceling out the '9', and making the 3600 to be '400'.. 

So the problem should look like: a = 400 <--- (Answer) 

Hope it helped.. :)
