━━━━━━━━━━━━━━━━━━━━

✰✰ ANSWER ✰✰

$\longmapsto\tt{Given\:No:.=\dfrac{-15}{8}}$

$\longmapsto\tt{Sum\:of\:Numbers=-9}$

$\longmapsto\tt{Let\:other\:number\:be=x}$

☛A.T.Q : -

$\longmapsto\tt{\dfrac{-15}{8}+x=-9}$

$\longmapsto\tt{x=\dfrac{-9}{1}+\dfrac{15}{8}}$

$\longmapsto\tt{x=\dfrac{-72+15}{8}}$

$\red\longmapsto\:\large\underline{\boxed{\bf\green{x}\orange{=}\purple{\dfrac{-57}{8}}}}$

_______________________

☛VERIFICATION : -

$\longmapsto\tt{\dfrac{-15}{8}+\dfrac{(-57)}{8}=-9}$

$\longmapsto\tt{\dfrac{-15}{8}-\dfrac{57}{8}=-9}$

$\longmapsto\tt{\dfrac{-15-57}{8}=-9}$

$\longmapsto\tt{\cancel\dfrac{-72}{8}=-9}$

$\longmapsto\tt{-9=-9}$
