Answer 2

$let \: the \: \: first \: rational \: number \: be \: \: \: x \\ \\ then \: according \: to \: the \: question \: \\ \\ \frac{4}{9} + x = \frac{28}{27 } \\ = > \: x \: = \frac{28}{27} - \: \frac{4}{9 } \\ = > \: x \: = \frac{16}{27} \\ \\ by \: this \: we \: get \: that \: \: the \: another \: no. \: is \: \frac{16}{27}$
