Answer 2

Explanation:

1.The product of a number and its reciprocal is 1

ex:-

A number = 2

Reciprocal of 2 = 1/2

Their product = 2×(1/2)=2/2 = 1

2.The rational number zero has no reciprocal.

The number = 0

Reciprocal = 1/0 = not defined

Reciprocal of zero is not defined

3.The rational number 0 is neither positive nor negative.

O is the number which is neither positive nor negative .It lies between positives and negatives on the number line

4. 0 is the only rational number which is equal its additive inverse.

The number = 0

Additive inverse = -0 = 0

Number = Additive inverse = 0
