it is not the simplest form. the simplest form would be 1/3. this is because with such a fraction as 11/33, you have a common factor with them, which is 11. reduce the fraction until there are no common multiples for the numerator and demonimator.
33=11+11+11 so 11/33=11/(11+11+11) represent a third part of an integer so 11/33=11/(3x11)=(11/11)x(1/3)=1/3=0,(3) can be simplified by 11, so its not simple form as 1/3 is
