I am trying to convert age written as years and month in to a decimal, where 12.06 (12yrs6mnths) would equal 12.5yrs).
I am a relative novice in formula writing and this is my best effort so far using =if to convert an age to it's decimal equivalent, but I'm getting a parse error. Any help greatly appreciated.
