The product of two rational numbers is always a rational number.
Two ninths, as a fraction, is represented as ( \frac{2}{9} ). When considering it as a whole number, it does not convert to a whole number since it is less than 1. Therefore, two ninths is simply a fraction that represents a part of a whole, specifically two parts out of nine equal parts.
