How would you writ the set of all recipricols of the natural numbers? I think it's (1/1 (I don't know if 1/1 is considered part of it) 1/2,1/3, 1/4, 1/5...) Is this correct? thanks

A reciprocal is the fraction turned upside down. A fraction multiplied by its reciprocal equals 1/1 or 1.
1/2 = 2/1 = 2/2

The reciprocal of 1/2 = 2/1
1/2 * 2/1 = 2/2 
Alright so how would you write that as a set like the one i mentioned above. Like the set of natural numbers is (1,2,3,4,5,6...), so would the set of all recipricols of natural numbers be (1/1, 1/2, 1/3...)

Seems right to me.

Alright thanks
