Vocabulary Review: Categorize each statement as true or false.
All mathematical expressions can be written as an equivalent expression with a denominator of 1.
An real number can have a denominator equal to 0.
The expression above a fraction bar is called the denominator.
Multiplying both the numerator and denominator by the same nonzero number results in an equivalent fraction.
