Question

the sum of two rational numbers is 13 by 5 one of them is 22 by 5 find the second number

Answer 1

let the other rational no be x
ATQ
$\frac{22}{5} + x = \frac{13}{5} \\ x = \frac{13}{5} - \frac{22}{5} \\ x = \frac{13 - 22}{5} \\ x = - \frac{9}{5}$
the other rational no be -9/5

Answer 2

$\bf{\underline{\underline \blue{Solution:-}}}$

$\sf\underline{\red{\:\:\: AnswEr:-\:\:\:}}$

• $\textbf {The second number = }$$\mathsf {-\frac{9}{5} }$

$\sf\underline{\red{\:\:\: Given:-\:\:\:}}$

• The sum of two rational numbers is 13 by 5 one of them is 22 by 5.

$\sf\underline{\red{\:\:\: Need\: To\:Find:-\:\:\:}}$

• The Second number = ?

$\bf{\underline{\underline \blue{Explanation:-}}}$

Let the second number = x.

$\sf\underline{\red{\:\:\: Now,\:A.T.Q:-\:\:\:}}$

$\dashrightarrow \sf {x + \frac{22}{5} = \frac{13}{5} }$

$\dashrightarrow \sf {x = \frac{13}{5} - \frac{22}{5} }$

$\dashrightarrow \sf {x = \frac{13 - 22}{5} }$

$\dashrightarrow \sf {x = -\frac{9}{5} }$

$\sf\underline{\red{\:\:\: ThereFore:-\:\:\:}}$

• $\textbf {The second number is }$$\mathsf {-\frac{9}{5} }$
