Question 951752: A solution has an alcohol/water ratio of 2 to 3. What is the percentage concentration of alcohol?

You can put this solution on YOUR website!
The % concentration is:
( amount of alcohol ) / ( amount of entire solution )
---------------------
I can say that there are any amounts I choose
as long as the stated ratio is true, so
I will say:
+2%2F3+=+400%2F600+
Alcohol = +400+ ( say liters for units )
Water = +600+ ( say liters for units )
Alcohol + Water = +400+%2B+600+=+1000+ liters
---------------------
% concentration of alcohol =
+400+%2F+1000+=+40%2F100+
+4%2F100+ = 40% alcohol
