You've already learned about percentages and how to convert decimal points into percentages. If you recall, a percentage is simply a way in which you can express a fraction in portions of 100. In this way if you were to see an item for sale at 100% off, it would mean that the item was free. If it was on sale at 90% off, you would multiply the original sales price, let’s say the original price was \$12.00, by .90 as .90 is the same as 90/100 or 90%. Remember that the symbol for percent (%) is converted to a decimal point by moving the decimal point two spaces to the left. Now getting back to the problem, it would read:

\$12.00 x .90 = \$10.80
