[tex]\frac{3}{5} - \frac{3}{5} (1 - \frac{1}{3} ) = \frac{3}{5} - \frac{3}{5} * \frac{2}{3} = \frac{3}{5} - \frac{2}{5} = \frac{1}{5}[/tex]
Stąd odpowiedź : A
Odpowiedź:
[tex]\frac{3}{5}-\frac{3}{5}*(1-\frac{1}{3})=\frac{3}{5}-\frac{3}{5}*(\frac{3}{3}-\frac{1}{3})=\frac{3}{5}-\frac{\not3^1}{5}*\frac{2}{\not3_{1}}=\frac{3}{5}-\frac{2}{5}=\frac{1}{5}\\\\Odp.A[/tex]
