No, Carlotta is not correct. A rational number can be expressed as a fraction of two integers, while an irrational number cannot. In the case of 23, it can be expressed as a fraction 23/1, making it a rational number. Furthermore, the decimal representation of 23 is not endless and does not equal 0.666666... The decimal representation of 23 is simply 23.
