see here is wehre your wrong keefe, .33333333 repitent * 3 equals .9 repitent on your calc, but nto in real life. cuz you can never get the true value of .9 repitent since it goes on forever, unless it is a fraction. 1/3 is teh true value of .3 repitent.  if you take the true value of teh decimals you will get one, but if you take the approximations on your calc and multiply by 3, you will get and approximation answer, i.e. .9
