Your comment puzzles me.  The answer I gave is, " Lb must be 11 1/9% longer than La" and is the same answer as Andrew gave:  "The answer from the choices will be 11 1/9."

Also, the process is better --  there was no rounding and the unnecessary (TMI) calculations were excluded.  Further, I included wise advice for approaching a problem and understanding distractors (wrong answers).

Thus, your statements are misguided.  You may have any expert read and analyze these posts -- if they know what they are talking about, they will agree.

Best wishes anyway!!
