1/2 L

Step-by-step explanation:

She makes 1 1/2 L of lemonade i.e. 3/2 L of lemonade.

She pours 1/4 of liter of lemonade into a thermos to take to the park. The amount of lemonade left is:

3/2 - 1/4 = 1 1/4 L = 5/4 L

Her brother drinks 2/5 of the remaining lemonade. The amount of lemonade that her brother drinks is:

2/5 * 5/4 = 1/2 L

Her brother drinks 1/2 L.
