There are 12 grams of sugar in 1⁄3 of a piece of candy. How much sugar is in 3⁄4 of a piece of candy?

Simply multiply twelve by three, giving you 36 grams in a full piece of candy, and then divide it by four, nine, and multiple nine by three: twenty seven (27). This is a somewhat roundabout way of doing it but this will work every time you do this kind of problem. (plus its the only way i know how to do it.)
