There is a kind of clothes in the shop. The original price is 40 yuan per piece, but after the price reduction, it's only 34 yuan per piece. How much cheaper is it?
(40-34) △ 40 = 6 △ 40 = 15% a: it's 15% cheaper
Percentage = percentage = 0.375 = (): 40 = 24 △ (). Quick
5 = 0. 375 = (15): 40 = 24 ^ (64)
