Fractions
Keys
1. %N lets you enter mixed numbers and
fractions. The unit must be an integer. The
numerator and denominator can contain
decimals.
To enter a mixed number, enter an integer for
the unit, and then press %N to enter a
numerator.
In MathPrint™ mode, pressing %N before
entering an integer displays a fraction
template, and allows only one digit to be
entered for the unit.
2. q lets you enter a simple fraction. Pressing
q before or after a number can result in
differing behavior. In MathPrint™ mode,
entering a number before pressing q usually
makes that number the numerator.
q in MathPrint mode can also be used for
more complex fractional or formula
computations that include operators and
other functions by pressing q before you
enter the numerator.
In MathPrint™ mode, press $ between the
entry of the numerator and the denominator.
In Classic mode, press q between the entry
of the numerator and the denominator.
3. % O converts a simple fraction to a
mixed number or a mixed number to a simple
fraction.
4. % j converts a fraction to its decimal
equivalent or changes a decimal to its
fractional equivalent, if possible.
Notes
• The examples on the transparency masters
assume all default settings.
• In MathPrint mode, fractions with q can
include operation keys (T, V, etc.) and most
function keys (F, %_, etc.). In Classic
mode, fractions with q do not allow
operation keys, functions, or complex
fractions in the numerator or denominator.
• In MathPrint mode, you can enter variables (x,
y, z, t, a, b, and c) in the numerator and
denominator of a fraction. In Classic mode,
fractions with q do not allow variables.
• In Classic mode, data editor, and table, use
W along with D and E where needed to
perform complex division problems.
