1. GIVEN:

   Sum of two rational numbers is -5

   One number is -3/5

   SOLUTION:

   Let’s just assume ‘x’ to be the second number,

   ∴ According to the question,

   ==> x – 3/5 = -5

   ==> x = (3/5) – 5

   ==> x = (3 – 25)/5 [LCM]

   ==> x = -22/5

   ∴ Required number is -22/5

2. Answer:

   let the other rational number be X

   given sum = -5

   that implies X + (-3/5) = -5

   X – 3/5 = -5

   X = -5+3/5

   X = (-25+3)/5 (taking LCM for denominators)

   X = -22/5

   therefore, the value of the other rational number is -22/5
