Given a < b < 0, to determine which inequalities is not correct, we need to analyze each one:

Option A, a + 6 < b + 6

Adding the same number to both sides of an inequality preserves the direction of the inequality. If a < b, then a + 6 < b + 6. So, this inequality is correct.

Option B, a/b > 1

Given a < b < 0, dividing both sides of a < b by b (a negative number) will flip the direction of the inequality: a/b > b/b Þ a/b > 1. So, ...
