Question

10. The sum of two rational numbers is -5/11. If one of the numbers is 3/13 find the other.​

Answer 1

Sᴏʟᴜᴛɪᴏɴ :-

Points to be remembered

• Sum of no.'s = -5/11
• Let the numbers be x , y
• So , given on of the no. is 3/13 , so either x or y = 3/13 . Lets take ‘x’

So by the given information , x + y = -5/11

⇒ x + y = -5/11

⇒ 3/13 + y = -5/11

⇒ y = -5/11 - 3/13

⇒ y = ( -65 - 33 )/143

⇒ y = -98/143

Hence , y = -98/143

Answer 2

Step-by-step explanation:

Let the other number be x

ATQ

$x + \frac{3}{13} = \frac{ - 5}{11} \\ \\ \sf\longmapsto x = \frac{ - 5}{11} - \frac{3}{13} \\ \\ \sf\longmapsto x = \frac{ - 65 - 33}{143} \\ \\ \sf\longmapsto x = \frac{ - 98}{143}$
