This number belongs to: integers $ZZ$ , rational numbers $QQ$ , and real numbers $RR$ . See explanation.

Before finding out in which sets the number is located we have to write it in the simpliest form:

$-144/3=-48$

The result is an integer number (the minus sign says it is not a natural number).

All integer numbers are also rational and real, so $-144/3=-48$ also belongs to the mentioned sets.
