Rule 2: Zero in the Numerator of a Simple Fractions

A numerator is allowed to take on the value of zero in a fraction. Any legal fraction (denominator not equal to zero) with a numerator equal to zero has an overall value of zero.

This means tex2html_wrap_inline44 , tex2html_wrap_inline46 , tex2html_wrap_inline48 all have a fraction value of zero because the numerators are equal to zero.

Example 1: Find the numerator, denominator, division symbol, and value for the simple fraction tex2html_wrap_inline50 .

Answer. The numerator is 0, the denominator is 9, the division symbol is -, and the value of the fraction is 0 because the value of the numerator is zero.

Example 2: Find the numerator, denominator, division symbol, and value for the simple fraction tex2html_wrap_inline52 .

Answer. The numerator is 0, the denominator is -11, the division symbol is -, and the value of the fraction is 0 because the value of the numerator is zero.

Example 3: Find the numerator, denominator, division symbol, and value for the simple fraction tex2html_wrap_inline54 .

Answer. Not a legal fraction, no value because the denominator is not allowed to have a value of zero. (See Rule 1).
