Answer 16

So we see that -5 is an integer. It is a rational number because it can be written -5/1.
It is a real number because it is rational.

Answer 17

I think you may be misunderstanding the question. The question is stating that -5 is all of the listed number sets with the exception of one set. @Mertsj just provided an excellent explanation of why -5 is an integer, why its rational, and why it is real. Does this make sense to you? @samtab ?
