There are 1.5 ounces in a shot. There are 64 ounces in a half gallon. So there are 42.6666667 shots in a half gallon or about 42 1/2 shots in a half gallon. You can find this out by going to Google and typing: shots in half gallon or the long way by typing: ounces in shot and ounces in half gallon
Close but a little off. You can round it to 17 shots in a fifth. A standard shot is indeed 1.5 ounces, and a fifth is 750 millileters. There are 44.36 mL in each 1.5 oz shot. doing the math, there are 16.907 1.5oz shots in a fifth. Not off by much really, but the extra mil and a half would be nice :)
