Question 4 . Express 0.99999 .... in the form p/q .Are you surprised by your answer? With your teacher and classmates discuss why the answer makes sense.

    It can be directly 9-0/9
    By a formula all bumbers -non repeating numbers / (9 for number of repeatimg numbers ) (0 for number of repeating numbers after decimal)

    Exampel ; 1.29890909090909.....
    129890-1298 / 99000
    128592 / 99000
