Rewording, half liter of wine is added to one liter of 20% water.
This cuts 20 into three parts and then counts two of those parts.

Total amount of mixture: one liter plus half a liter = 1.5 liters

Amount of water: 20% of one liter = 0.2 liters

Fraction of mixture that is water: 0.2/1.5 = 2/15

Percentage of mixture that is water: 100(2/15) = 200/15 = 40/3 = 13 1/3

ANSWER: 13 1/3%
