Answer 2

Heya !!!

Let other Rational Number be X .

One Rational Number = -9/20

According to question,

Sum of two rational Numbers = -3.5

One Number + Other Number = -3.5

-9/20 + X = -3.5




-9 + 20X /20 = -3.5



-9 + 20X = -3.5 × 20



-9 + 20X = -70



20X = -70+9


20X = -61



X = -61/20

Hence,

Other Rational Number = X = -61/20
