Are some rational numbers integers?

1 Answer

Apr 2, 2016

Yes. All integers are rational numbers, but not all rational numbers are integers.

Explanation:

A number is called rational if it can be expressed in the form $\frac{p}{q}$ $p/q$ for some integers $p$ $p$ and $q$ $q$ , with $q \neq 0$ $q != 0$ .

Any integer $n$ $n$ can be expressed in such a way as $\frac{n}{1}$ $n/1$ , so is a rational number.

Not all rational numbers are integers. For example, $\frac{1}{2}$ $1/2$ .

So some rational numbers are integers.
