Question

Is 0.28 rational or irrational?

Answer 1

`\huge\boxed{\text{rational}}`

`0.28` is a rational number because it has a known end in its decimal form.

An example of an irrational number would be
`74.9\overline{3}`. This number does not have a defined end. It goes
`74.933333333333...` and never ends, making it irrational.
