Question: how to work out percentage saving?
Answer: In this example, that's $10 divided by the original $50 price tag, or 0.2. Multiply the decimal by 100 (or move the decimal point over two spaces to the right) to convert it to a percentage. In this example, that's 0.2 multiplied by 100, or 20 percent. This means you saved 20 percent on the purchase of the sweater.
