  2. 27 over 100
    Is my explanation correct?
    27 is repeated as it has a dot on its 2 number.This means that the real value is about 0.272727272727.....100 = 1 in fraction.27 over 100 is a fraction.Thus the answer is 27 over 100

  3. 3/11
    Explanation:let "x" be 0.27...
    100x= 27.27....
    100x - x=27.27... - 0.27...
    99x=27
    x=27/99
    =3/11
