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?
Jake drank 8/2=<T>divide(8, 2)=4.0 shots
So he drank 4*1.5=<T>multiply(4, 1.5)=6.0 ounces of vodka
That means he drank 6*.5=<T>multiply(6, 0.5)=3.0 ounces of pure alcohol
