nine and seven twelfths
Five twelfths plus eight twelfths equals thirteen twelfths. To simplify this fraction, we can divide both the numerator and the denominator by their greatest common factor, which in this case is one. Therefore, thirteen twelfths cannot be simplified further, and it is the final result of adding five twelfths and eight twelfths.
We convert this to twelfths to give: 10 twelfths + 4 twelfths + 9 twelfths = 23 twelfths or 1 and 11 twelfths.
