Ok, so the premixed cans I had after work tonight were 4.8% alcohol and 375ml, and the bottle i’m drinking from now is 37.0% alc/vol (Jim Beam) My question is, how much 37% would I have to mix with 2L of coke to make it an equivalent to the cans? and/or to fill my glass, which is ~300ml, how much of each would I need?.. Thanks, and I hope you can excuse my inability to work this out at the moment! 
If you mix it half and half you will have a solution with 18.5% alcohol.
If you mix it 3 parts to 1 you will have a solution with 9.25% alcohol.
If you mix it 7 parts to 1 you will have a solution with 4.625% alcohol, which is close enough.
So, put about 40 ml of Jim Beam in your glass and top it up with Coke. Although why you would want to mix it with Coke is another story.
Why you would want to drink Jim Beam is a bigger mystery. 74 proof? They’ve been watering down the booze more and more every year. By 2020 that bottle will register as “alcohol-free.”
Remember kids, math and alcohol don’t mix, so
Please don’t drink and derive.
This kind of linear thinking is why our society will never be fully integrated.
I just got a T-shirt with this on it. It has a “dy/dt” symbol on it, with the “Y” a martini glass. It’s inside a red circle with a diagonal slash over it.

Or homeopathic booze.
It would cure a hangover!
Wait a minute, that might actually be correct.
One of the professors here has a mug with that on it, followed by a bunch of equations that are wrong in subtle but hilarious ways, like F = m*a.
I shouldn’t find that funny, but I do.
OK, I’ll bite. I assume the joke is somewhere in using a programmer’s multiplication symbol where the usual equation would be written out “F=ma”, but is that itself the joke? Because I don’t get it then.
Two of the letters in that equation are in bold. Admittedly, the joke works better with arrow marks over the vectors (which I think is how it is on the mug), but that’s not supported on the board.
mix 38.92 mL of Jim Beam with 261.08 mL of Coke to get 300 mL.
mix 48.65 mL of Jim Beam with 326.35 mL of Coke to get 375 mL.
