How do you write a rational number as a decimal?
You divide the numerator of the rational expression by its denominator.
How do you determine the values for which a rational expression is undefined?
A rational expression is not defined whenever the denominator of the expression equals zero. These will be the roots or zeros of the denominator.
What are algebraic fractions whose numerator and denominator are polynomials?
A rational fraction.
When writing an equivalent rational expression why do you multiply both the denominator and numerator by the same factor?
Because you need to maintain the ratio between the two numbers at the same value.
What fraction having rational expression in its numerator or denominator or both?
If you divide a rational expression by another rational expression, you will again get a rational expression.

When is a rational expression Simplified?
When the only common factor between numerator and denominator is 1.
The first step in reducing a rational expression is to do what to both the numerator and denominator?
To reduce a fraction to its lowest terms divide the numerator and the denominator by their highest common factor
What are some Rational expression examples?
Just write ANY fraction, with a polynomial in the numerator, and a polynomial in the denominator.
What is true about both the numerator and denominator of rational expressions?
Both the numerator and denominator are polynomials
When is a rational expression written in its simplest form?
When the numerator and denominator are coprime - ie have no factor in common other than 1.
