9/81 is equivalent to which fraction? please explain
alexdok [17]
9/81 can be simplified into 1/9. You divide both the top and bottom part of the fraction by 9.
9/9=1 and 81/9=9 to get 1/9. but that's it's simplified version. equivalent fractions of it can be almost anything. like, 1/9 can equal 2/18, 3/27, or 4/36.
