1.	The sum of two rational number is -4 If one of then is -11/5, find the other
Answer» Given $\bold{Sum \ of \ 2 \ rational \ numbers} = -4\\\\\bold{One \ of \ the \ rational \ <klux>NUMBER</klux>} = \dfrac{-11}{5}$ Let the other number be X $\implies \dfrac{-11}{5}+ x = -4\\\\\implies x = -4 + \dfrac{11}{5}\\ \\\implies x = \dfrac{-20+11}{5} \\\\\implies x = \dfrac{-9}{5}$ $\boxed{\boxed{\bold{Therefore, \ the \ other \ number \ is \ \frac{-9}{5}}}}}$
