I just cant work this out , i havnt used my Mathematica skills that much recently it must be said, but im sure someone will be able to answer this.
Bottle of wine = 750 cl, 12.5%
Bottle of Smirnoff = 700 cl, 37.5%
So you have an empty wine bottle, your going to add X amount of vodka, top up with slim line lemo, and maybe a little ginger cordial, how much vodka do you put into the bottle to make the same % as the wine?
thanks!
