What is 1 1/12 as a mixed number

1 1/12 is already a mixed number unless you mean eleven over 12. If so 11 can't be a mixed number since it is less than the denominator. If any numerator (aka the number before the / ) is less than the denominator (aka the number after the / ) then it is impossible for it to be a mixed number
