Question

The sum of two rational numbers is -13/7.If one of the numbers is 7/13,fine the other

Answer 1

let the ration number be X

ATQ

$x + \frac{7}{13} = - \frac{13}{7} \\ or \: \: x = - \frac{13}{7} - \frac{7}{13} \\ or \: x = \frac{ - 169 - 49}{91} \\ \: \: x = \frac{ - 218}{91}$

this is the answer

Answer 2

Hello!

Sum of two rational numbers =

$\frac{ - 13}{7}$

One of the rational number =

$\frac{7}{13}$

Solution

$\frac{7}{13} + x = \frac{ - 13}{7}$

$x = \frac{ - 13}{7} - \frac{7}{13}$

LCM of 13,7= 91

$x = \frac{ - 169}{91} - \frac{49}{91}$

$x = \frac{ - 218}{91}$

Hopefully helps!
