Question

If we multiply (or divide) both sides of an inequality by a negative number, then the sign of inequality changes.
If $(-8)(-2)>(-7)(-2)$, then

• A. $-8>-7$
• B. $-8<-7$
• C. $-8\ge -7$
• D. $-8\le -7$

Answer 1

Answer: (B)

In the given inequality $(-8)(-2)>(-7)(-2)$, divide both sides by $-2$. Since $-2$ is a negative number, sign of inequality will change. Hence, $-8<-7$.
