# How do you find the set in which the real number -144/3 belongs?

Nov 30, 2016

This number belongs to: integers $\mathbb{Z}$, rational numbers $\mathbb{Q}$, and real numbers $\mathbb{R}$. See explanation.

#### Explanation:

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

$- \frac{144}{3} = - 48$

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 $- \frac{144}{3} = - 48$ also belongs to the mentioned sets.
