my instructor uses a form of proportions for percents. l like to use old fashion way by multiplying ordividing to get my answer, l need an easier way. also area,perimeter, and triangle that it so confusion when you get questions that have about six numbers going around a box in inches,cm, and mm? and if course there is more moslty your basic 060 math (college math)
