whats the question

Develop a proof to show that \[a ° b =\frac{a+b}{ab}\]Has no identity (i.e. \(a ° b = a\)).

Any clue?

Here is what I got

Is that ever true?
Let's use some real numbers:
7 * 3 = (7 + 3) / 7*3
7*3 =? 10/21
21 =? 10/21

Why do we assume that a*b = a?

for all a belonging to the required set

@Nishant_Garg, the \(ab\) should be at the bottom, not the top

oh wow my bad haha

Yeah, that changes a bit ;)

but it should be something like that if u just solve it

I don't know how to rearrange to get something similar, can you help @Nishant_Garg?

ill try

Thanks so much @Nishant_Garg :D

Yeah. Thanks so much @Nishant_Garg :D
