Provide an appropriate response.If a < b, is it always true that 
> 
? Explain.
What will be an ideal response?
Explanations will vary. One possible answer:No. The second statement only follows from the first if a and b are either both positive or both negative. Divide both sides of the original inequality by (ab). If a and b are of opposite signs, then (ab) < 0. When dividing by a negative number, the inequality sign must be reversed 
.In addition, if a (or b) is zero, then its reciprocal is undefined.
