On TV or radio, we have heard that a bank has had a 7 percent of profits. That means that for every 100 coins, it has earned 7 times more and now it has 107 coins. The percentage of profit was 7%.

Another example: there was a VAT law that stipulated that all traders had to pay to the State a tax of six percent (6 %) of all sales. If a store has sold 100 Euros, it will pay 6 Euros to the state; if it had sold 200 Euros, it would have to pay 12 Euros.
