Suppose a 90 dollar item was on sale for 72 dollars. What is the percentage change? Find the difference. 90 - 72 = 18. 18 is 1/5 of 90 or 20%. The percentage of decrease is 20%. Since we subtracted 20% from the original number, the remainder must be 80%. 72 is 80% of 90. (90 x 0.80 = 72)
It is: 72%
% rate= 72/80 * 100%= 0.9 * 100%= 90%
(72/90) * 100
90% of 72 = 90% * 72 = 0.9 * 72 = 64.8
