Example:

Suppose you have a 56 3/4–inch space that you want to divide into six equal sections. How wide is each section, assuming you can conveniently measure 1/16– inch increments? What's the cumulative roundoff error?

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.
