Answer 1

ANSWER


The set of all rational numbers and the set of all real numbers.


EXPLANATION

The set of rational numbers contains all numbers that can be written in the form,


$\frac{a}{b}$


where a and b are integers and b≠0.


The given number is

$- \frac{1}{2}$


It belongs to the set of rational numbers.


The set of rational numbers is a subset of the set of real numbers.

Hence

$- \frac{1}{2}$
also belongs to the set of real numbers.


The correct answer is A.
