Question

the sum of two rational numbers is 18/-25, if one of the rational numbers is 7/10,find the other

Answer 1

Answer:

$x + \frac{7}{10} = - \frac{18}{25}$

$x = - \frac{18}{25} - \frac{7}{10}$

$x = - ( \frac{18}{25} + \frac{7}{10} )$

$x = - ( \frac{36 + 35}{50} )$

$x = - \frac{71}{50} = ( - 1 \frac{21}{50} )$
