$\huge\bf\pink{\mid{\overline{\underline{Answer :- }}}\mid}$

$\sf{\huge{\underline{\orange{Given :-}}}}$

• The sum of two rational number is -4/3.

• One of the number is -5

$\sf{\huge{\underline{\purple{To\:Find :-}}}}$

• The other number.

$\sf{\huge{\underline{\red{Answer :-}}}}$

We have,

One number is -5 .

According to the question,

The sum of two rational number is -4/3.

x + (-5) = -4/3

➝ x - 5 = -4/3

➝ x = - 4/3 + 5

➝ x = $\dfrac{ - 4 + 15}{3}$

➝ x = 11/3

$\sf{\huge{\underline{\green{Verificaton :-}}}}$

x + (-5) = - 4/3

➝ x - 5 = - 4/3

➝ 11/3 - 5 = - 4/3

➝ 11/3 - 15/3 = -4/3

➝ -4/3 = -4/3

Answer 2

Given:-

• Sum of two rational number ${\bold{= \dfrac{-4}{3}}}$.

• One of the number = -5

To Find:-

• The other number.

Solution:-

Let the other number be x.

According to question,

⟾ Sum of two rational number = $\dfrac{-4}{3}$

⟾ x + (-5) = $\dfrac{-4}{3}$

⟾ x = $\dfrac{-4}{3}+5$

⟾ x = $\dfrac{-4+15}{3}$

⟾ x = $\dfrac{11}{3}$

Hence, the other rational number is ${{\bold{\dfrac{11}{3}.}}}$
