A common situation wherein knowing how to get percentages is helpful is when out shopping during a sale. For example, a sweater is originally \$150 but has a 20% discount. To obtain the percentage, or the amount saved, the percent value is first divided by 100, making it 20/100, or 0.2. The answer is then multiplied by the original price: 0.2 X \$150, giving an answer of \$30 saved. This means the sweater is now only \$120.
