Question

-9 is a rational number

Answer 1

Yes, -9 is a rational number. A rational number is any number that can be expressed as the quotient or fraction \( \frac{a}{b} \), where \( a \) and \( b \) are integers and \( b \) is not zero. In this case, -9 can be expressed as \( \frac{-9}{1} \), which qualifies it as a rational number.
