Rule 1: Division by Zero in a Simple Fraction

### **The denominator of
any fraction cannot have the value zero. If the denominator of a
fraction is zero, the expression is not a legal fraction because it's
overall value is undefined**

This means ,
, are not legal fractions.
Their values are all undefined, and hence they have no meaning. Once
you encounter such a fraction in a problem, stop. You cannot proceed
with the problem.

**Example 1:** Find the numerator,
denominator, and division symbol for the simple fraction .

**Answer.** There is no numerator, no
denominator, no division symbol because it is not a legal fraction. The
denominator can never be zero in any fraction.

**Example 2:**
Find the numerator, denominator, and division symbol for the simple
fraction .

**Answer.** There is no numerator, no denominator, no division
symbol because it is not a legal fraction. The denominator can never be
zero in any fraction.

**Example 3:** Find the numerator,
denominator, and division symbol for the simple fraction .

**Answer.** There is no numerator, no denominator, no
division symbol because it is not a legal fraction. The denominator (2
-2) = 0 and the denominator can never be zero in a fraction.
