The identity property for multiplication states that
a * 1 = a Therefore it would seem that
a/1 = a So I would pick a.

What I know by identity property for multiplications. , in the field of real (and even complex) numbers, os the one that says there exists an element 1 such that a *1 = 1* a = a.
But there's no real number x such that a/x = x/a for every real a. So, this property is not trus for division even if you take x =1. Answer b, false.

They're both the same. You just substitute the sign.
