Fractions in Equations
When you're typing an equation, you can't type a number as a fraction. When an
equation is displayed, all numeric values are shown as decimal values —
Fraction–display mode is ignored.
When you're evaluating an equation and you're prompted for variable values,
you may enter fractions — values are displayed using the current display format.
See chapter 6 for information about working with equations.
