Let the number be x

$\sf \large \frac{ - 5}{9} + x = 1$

$\sf \: x = 1 - \frac{5}{9}$

L.C.M. of 1 and 9=9

$\implies \frac{1}{1} \times \frac{9}{9} = \frac{9}{9} \\ \\ \implies \frac{5}{9} \times \frac{1}{1} = \frac{5}{9} \\ \\ \implies \frac{9 - 5}{9} = \frac{4}{9}$

So $\large \frac{4}{9}$should be added to $\large\frac{ - 5}{9}$to get 1
