Every integer is a rational number.
True or false

Every integer is a rational number. The statement is true. An integer is a number with no decimal or fractional part, from the set of negative and positive numbers, including zero.

For example, lets use the integer, -5.

If it was rational number it would need to be either a decimal or fraction.

So -5 is not a rational number and is an integer.

If the number was 0.5 or 1/5, the number would have been rational.

Inconclusion your statement is true.
