Alexa has  \(\frac{5}{9}\)  of Karl's money. How much must Karl give Alexa so that both will have the same amount?

 

Hello Guest!

 

\(k=495\\ a=\frac{5}{9}\cdot495\\ \frac{x}{2}=k-a=495-\frac{5}{9}\cdot495=\frac{4}{9}\cdot 495=220\\ \)

\(x=110\)

$110 must Karl give Alexa so that both will have the same amount.
