Answer 1

-1∉ N -1∈ Z -1∈ Q 7/12 ∉ N 7/123 ∉ Z 7/123 ∈ Q 3,05 ∉ N 3,05 ∉ Z 3,05 ∈ Q

-2,3 ∉ N -2,3 ∉ Z -2,3 ∈ Q 1035 ∈ N 1035 ∈ Z 1035 ∈ Q

Tick cho mình nha

Answer 2

-1 \(\notin\) N ; \(-1\in Z\) ; \(-1\in Q\) ;\(\dfrac{7}{12}\notin N\);\(\dfrac{7}{123}\notin Z;\dfrac{7}{123}\in Q;3,05\notin N;3,05\notin Z;3,05\in Q\)

\(\dfrac{-2}{3}\notin N;\dfrac{-2}{3}\notin Z;\dfrac{-2}{3}\in Q;1035\in N;1035\in Z\)

\(1035\in Q\)
