Question

the sum of two rational number is -5 .if one of them is -13/6, find the other

Answer 1

Step-by-step explanation:

$let \: other \: rational \: number \: be \: x$

$one \: rational \: number = \frac{ - 13}{6}$

$sum \: of \: two \: rational \: numbers = - 5$

$according \: to \: question$

$x + ( \frac{ - 13}{6} ) = - 5$

$x = - 5 - ( \frac{ - 13}{6} )$

$x = - 5 + \frac{13}{6}$

$x = \frac{( - 5 \times 6) + 13}{6}$

$x = \frac{ - 30 + 13}{6}$

$x = \frac{ - 17}{6}$

$other \: rational \: number \: = \frac{ - 17}{6}$
