We consider the quantities S (for Saima) and B (her brother).

We know that the ratio of S/B=50%=1/2.

The ratio B/S then equals to 2/1, or 200%.

Mathematically, we're considering the inverse of the ratio.

(S/B)^-1=B/S

You are missing numerous words. Salma is not "getting" a portion or her brother or vice versa.
