The fraction of orange juice is \( \frac{2}{5} \).
The remaining fraction of the mixture is:
\( 1 - \frac{2}{5} = \frac{3}{5} \),
which consists of sweet lime juice.
The fraction of pure fruit juice is:
\( \frac{2}{5} + \frac{3}{5} = \frac{5}{5} = 1 \).
The fraction of pure fruit juice is \( \frac{3}{3} = 1 \).
