Percent or percentage equates to hundredths. The new price for a pair of shoes originally priced at $130 and going on sale with a 15% reduction can be calculated in two main ways. 1) If 15% is taken off then 85% remains. 130 x 85/100 = 110.50 2) Calculate 15% and then subtract this amount from the original price. 15% of 130 = 130 x 15/100 = 19.50 : 130 - 19.50 = 110.50
