Answer 1

1/x + 1/y = 9/10

1/y = 9 /10 + 3/5

1/y = 15/10 ( LCM le lena shi se )

y = 10/15or 2/3

Answer 2

$\bold \pink{answer}$

$\sf{x + y = \frac{9}{10} }$

$given \: x = \frac{ - 3}{5}$

$\tt{so \: y = \frac{9}{10} - ( - \frac{3}{5} )}$

$= \frac{15}{10} = \frac{3}{2}$

The other rational number is 3/2..
