65% reduction means that 231 is: 100-65 % or 35% of the original price. create ratios to compare: 231/35 and x/ 100. t hese ratios should equal each other so: 231/35= x/100 cross multiply: 231 times 100= 35x simplify 23100=35x get x on its own by dividing by 35: 23100/35= x simplify: 660=x so the original price was $660
