1. Given:–

   • Sum of two rational number is 13/5
   • One of them is -21/7 = -3

   To Find:–

   • Second number ?

   Solution:–

   It is given that the sum of rational number is 13/5 .One number is -3 .

   Let the second number be x.

   According to the Question

   [tex]\longrightarrow[/tex] Sum of number = 13/5

   [tex]\longrightarrow[/tex] -3 + x = 13/5

   [tex]\longrightarrow[/tex] x = 13/5 + 3

   [tex]\longrightarrow[/tex] x = 13+15/5

   [tex]\longrightarrow[/tex] x = 28/5

   • Hence, the second number is 28/5 .

2. Step-by-step explanation:

   let the second number be x

   -21/7+x = 13/5

   x = 13/5+21/7

   x = 91+105/35

   x = 196/35

   x = 28/5
