Yes, both rational and irrational numbers can be negative. Rational numbers are any numbers that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. These numbers can be positive, negative, or zero. For example, -1/2, -3, and -5/4 are all rational numbers.

Similarly, irrational numbers are numbers that cannot be expressed as a simple fraction of two integers. These numbers also include negative values. For instance, -√2, -π, and -e are examples of irrational numbers that are negative. Therefore, both rational and irrational numbers can have negative values.
