Jake splits 8 shots of vodka with his friend.  Each shot of vodka is 1.5 ounces.  If the vodka is 50% pure alcohol, how much pure alcohol did Jake drink?
How many shots did Jake drink? ** Jake drank 8/2=<<8/2=4>>4 shots
How many ounces of vodka did Jake drink? ** So he drank 4*1.5=<<4*1.5=6>>6 ounces of vodka
How many ounces of pure alcohol did Jake drink? ** That means he drank 6*.5=<<6*.5=3>>3 ounces of pure alcohol
