Question

If abc > 0, such that a,b,c are integers then which of the following must be true?

• A. \(\frac{a}{b}\lt0\)
• B. \(\frac{ab}{c}\gt0\)
• C. bc < 0
• D. a > bc

Answer 1

The Correct Option is B

Since \(abc > 0\), this means the product of a, b, and c is positive. 
This implies that a and b must either both be positive or both negative. 
Therefore, the product ab is positive, and \(\frac{ab}{c}\) must also be positive.
