To determine which inequalities is not correct, we need to analyze each one.

Given the position of the rational numbers a, b and c on the number line, we have:

c < b < 0

a > 0

It implies c < b < a.

Option A, cb > ab

Since c < a, multiplying both sides by b, we have cb > ab. We need to flip the direction of the inequality because b is a negative number. So, this inequality is correct.

Option B, ac > ab

Since c < b, multip...
