What is the correct solution of x/(-4) > 1?

Answer and explanation

Correct answer: x < -4

The governing concept is that multiplying an inequality by a negative number reverses its direction. Begin with x/(−4) > 1. Multiplying both sides by −4 gives x < −4, because 1 × (−4) = −4 and the sign changes from > to <. Thus option B is correct. A numerical check makes the result clear: x = −5 gives (−5)/(−4) = 1.25, and 1.25 > 1 is true; also, −5 < −4. In contrast, x = −3 gives 0.75 > 1, which is false. Option A is obtained by forgetting the reversal. Options C and D have an incorrect endpoint or sign and do not describe the solution set of the original inequality.
