Answer 2

Answer:

(i) and (iii) are empty sets

Step-by-step explanation:

(i)  the natural number is starting from one and a natural number less than zero is a null set.

(iii) when the 2 goes to other side it becomes +2 and 15 goes to other side and become 2/15 and it is a proper fraction when we divide 2/15 we get decimal points and it is not a natural number so it is also a null set.
