2.31 is, itself, a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And you cannot get much closer to 2.31 than 2.31!Its equivalent, in rational form, is 231/100. That is its exact equivalent so, again, you cannot get any closer than that!
