Answer 2

$Sum \: of \: two \: rational \: numbers \: is =$

$- \frac{3}{2}$

$</p><p>Given \: one \: of \: the \: rational \: number =$

$- \frac{5}{8}$

$The \: other \: rational \: number = x$

$- \frac{ 5}{8} + x = - \frac{3}{2}$

$x = - \frac{3}{2} + \frac{5}{8}$

$lcm \: of \: 2 \: and \: 8 \: is \: 8$

$= \frac{ - 3 \times 4}{ 2 \times 4} = - \frac{ 11}{8}$

$by \: further \: calculation$

$\frac{ - 12}{8} - \frac{11}{8} \\ so \: we \: get \: = \frac{ - 12 - 11}{8} \\ = \frac{ - 23}{8}$
