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 #p/q# for some integers #p# and #q#, with #q != 0#.

Any integer #n# can be expressed in such a way as #n/1#, so is a rational number.

Not all rational numbers are integers. For example, #1/2#.

So some rational numbers are integers.
