maybe

anonymous · Answer

21 litres total, 3 of which are alcohol.
3/21 = 1/7.

i need another answer

anonymous · Answer

There's 12 litres of water. Add another 6 litres. That makes 18 litres. Plus 3 litres of alcohol makes 21.

anonymous · Answer

they 1/7 but how

anonymous · Answer

Because there's 21 litres total: 12 + 3 + 6 = 21. Of that, 3 litres are alcohol which is 3/21 which simplifies to 1/7 (divide 3 and 21 by 3).

anonymous · Answer

why did you add the alcohol 3

anonymous · Answer

Because it's part of the mixture. As a whole, it is 21 litres, including the 3 litres of alcohol. If it were separate, it wouldn't be a part at all.
