Common Fractions
A common fraction consists of a "numerator" (top number) and a "denominator" (bottom or ‘down’ number). A fraction is an expression of a "part" of a "whole" unit.
Example: The common fractions, 1/3 and 1/4, share the number "1" as a numerator, and the numbers "3 and 4" are the denominators.
Reminder! When the numerators of fractions are equal, the fraction with the lowest denominator has the "greater" value!
