You can do this two ways; (1) First change percent to a fraction by dividing by 100. So 20% becomes .2 . Now multiply times 25 to get .2 x 25 = 5 . So 20% of 25 is 5. Now subtract that from 25 to get the new price after getting 20% off; New Price = 25 - 5 = 20. (2) Getting 20% off, means instead of paying 100% you only pay 100% - 20% = 80%. So you change 80% to a fraction, by dividing by 100, then multiply times 25 to get the new price; New Price = .8 x 25 = 20.
