Fractions and Fraction Indicators

1. The opening and closing simple fraction indicators must be used to enclose a simple fraction whose numerator and denominator are separated by a horizontal fraction line.

   The horizontal fraction line must be shown by .

2. Simple fraction indicators must be used to enclose a simple fraction whose numerator and denominator are separated by a diagonal line when the numerator and denominator are printed at different levels of writing on either side of the diagonal line or in a different type size from that normally used for such fractions throughout the text. The diagonal fraction line must be shown by .
