Answer 2

Answer:

The other rational number is

$\boxed{\red{\sf\:-\:\dfrac{148}{19}}}$

Step-by-step-explanation:

Let the other rational number be x.

From the given condition,

$\sf\:x\:+\:\dfrac{15}{19}\:=\:-\:7\\\\\\\implies\sf\:x\:=\:-\:7\:-\:\dfrac{15}{19}\\\\\\\implies\sf\:x\:=\:\dfrac{\:-\:7\:\times\:19\:-\:15}{19}\\\\\\\implies\sf\:x\:=\:\dfrac{-\:133\:-\:15}{19}\\\\\\\implies\boxed{\red{\sf\:x\:=\:-\:\dfrac{148}{19}}}$
