§61. Simple Fractions: For the purposes of this Code, a simple Fraction is one whose numerator and denominator contain no Fractions except possibly at the superscript or subscript level.
§62. Use of SimpleFraction Indicators:
a. SimpleFraction indicators must be used, except in the case of mixed numbers, to enclose a simple Fraction whose numerator and denominator are separated by a horizontal Fraction line in ink print.
§63. NonUse of SimpleFraction Indicators:
a. SimpleFraction indicators must not be used to enclose the Fractional part of a mixed number.
