ikadub [295]

Answer:

a) False

b) False

Step-by-step explanation:

We are given the following information:

Z is a set of all integers, $Z^+$ is a set of all positive integers and $Z^-$ is a set of all negative integers.

Q is a set of all rational numbers, $Q^+$ is a set of all positive rational numbers and $Q^-$ is a set of all negative rational numbers.

N is a set of all natural numbers.

a) False

We will show this with the help of a counter example.

$Z = 3\\Q = \frac{3}{4}\\\displaystyle\frac{Z}{Q} = \displaystyle\frac{3}{\frac{3}{4}} = \displaystyle\frac{8}{3}$

which is a rational number and not an integer.

b) False

We will show this with the help of a counter example.

$Z = 3\\Z^- = -5\\\displaystyle\frac{Z}{Z^-} = \displaystyle\frac{3}{-5} = -\displaystyle\frac{3}{5}$

which is a rational number and not a natural number.
