problem in using symbols

Hi everyone I have a problem in my program. I have a symbol called 'f' in an equation when I write (3*10^-12)/(1-f) it is written in the command window as '1/(1237940039285380274899124224/3713820117856141-1237940039285380274899124224/3713820117856141*f_ES)'which is the same value but in much complex form. How can I make the program write it in the simple form? I use this equation in the remaining of the program and it become much harder to follow and calculate.
