5. (iv) 0/1
6. (v) -1
7. (vi) -1

Explanation:

1. no explanation- it is a fact
2. whole numbers are 0 and more, natural numbers are 1 and more. they both cannot be fractions.
3. integers are also not fractions. they cannot be parts. they HAVE to be whole.
4. non-negative means positive.
5. 0 is neutral, it is not positive or negative. it comes in the middle on the number line.
6. whole numbers cannot be negative but integers can.
7. integers have to be whole. they cannot be parts of a whole. and -1 is the first whole negative number.
