Show that the intervals (0,1) and [0,1] are equivalent. (Hint: consider rationals and irrationals separately).(adsbygoogle = window.adsbygoogle || []).push({});

I'm able to find a function that shows a bijection between (0,1) an [0,1] under the irrationals, but i can't figure out the rationals. Also... the next step (i believe) would be to find a bijection between these two functions. If anybody can help me figure out an answer to this problem that would be so awesome! Thanks so much, guys!
