Answer:
The exclusion placed on the variable x for the fraction is 0.
Explanation:
If the variable x is a fraction, then the variable x can have any value other than 0.
Because if the denominator of a fraction is zero, the expression is not a valid fraction because the fraction value will be undefined. This means if the variable x has value 0 then the fraction values are all undefined, and hence they have no meaning.
Hence, the exclusion placed on the variable x for the fraction is 0.
