Best ResponseYou've already chosen the best response.4If a=b, and they're not zero, you can divide both sides by ab to get 1/a=1/b.

Best ResponseYou've already chosen the best response.0It's been answered, but a more rigorous way of answering it would be:\[\left\{a=b\mid\forall \left(ab\neq0\right)\right\}\]

Best ResponseYou've already chosen the best response.0Whoops, I mean:\[\left\{a=b\therefore\frac{1}{a}=\frac{1}{b}\mid\forall \left(ab\neq0\right)\right\}\]

Best ResponseYou've already chosen the best response.0As either \(a,b\) can be \(0\), but not necessarily both, for the implication to be demonstrably false. A simpler way of showing this is by determining that the product must not be zero.
