It seems you have a small typo in your statement. The correct definition is that rational numbers can be expressed in the form \( \frac{a}{b} \), where \( a \) and \( b \) are integers, and \( b \neq 0 \).

This means that the denominator cannot be zero, as division by zero is undefined in mathematics. Rational numbers include integers, fractions, and any number that can be represented as a fraction of two integers, such as \( \frac{1}{2} \), \( \frac{-3}{4} \), or \( 5 \) (which can be written as \( \frac{5}{1} \)).

No, a rational number cannot ever have a denominator of zero. The definition of a rational number explicitly states that the denominator \( b \) must be an integer and must not equal zero (\( b \neq 0 \)).

If \( b \) were zero, the expression \( \frac{a}{b} \) would be undefined because division by zero does not yield a meaningful result in mathematics. So, all rational numbers must be in the form \( \frac{a}{b} \) where \( a \) and \( b \) are integers, and \( b \) is not zero.
