using all pairs of positive numbers a and b such that a>|b|, which lists all possible real values of a/b?
F. all real #s greater than 0 G. all real #s between 0 and 1 H. all real #s between 0 and 1, inclusive I. all real #s greater than 1 J. all real #s greater than or equal to 1

- I x = a/|b| a > |b| ⇒ x >1 If a and b are positive then a = |a|, b = |b|, so that's a distraction. UPDATE: if you want a limit formulation, consider the following ∀ a, b +ve, |a| > |b| ⇒ |a| > |b| + ε, ε > 0 ⇒ |a|/|b| = |a|/(|a| - ε) > 1
