If \(a>b\) and \(k<0\), which of the following statements is correct?

Answer and explanation

Correct answer: \(ak<bk\)

When both sides of an inequality are multiplied by a negative number \(k\), the inequality sign reverses. Thus, from \(a>b\), we get \(ak<bk\), so option B is correct. Option D is also incorrect because division by a negative number reverses the sign, giving \(\frac{a}{k}<\frac{b}{k}\). Exam tip: Reverse the inequality sign whenever you multiply or divide both sides by a negative number.
