Fractions in Equations
You can use a fraction in an equation. When an equation is displayed, all
numerical values in the equation are shown in their entered form. Also, fraction-
display mode is available for operations involving equations.
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.
