1. Step-by-step explanation:

   Let the number be x

   A/Q,

   [tex] \frac{ 2}{21} + x = \frac{ – 3}{7} [/tex]

   [tex]x = \frac{ – 3}{7} – \frac{2}{21} [/tex]

   [tex]x = \frac{ -9 – 2}{21} [/tex]

   [tex]x = \frac{ – 11}{21} [/tex]

2. Answer:

   let the other number is x

   so,

   2/21 +x= -3/7

   => x= -3/7-2/21

   => x=(-9-2)/21

   => x= -11/21

   so the other rational number is -11/21
