How percentage form our daily life? "I'll never need math again!" Everyone says this right after graduation. Everyone claims to have a little distance from our school year so, unfortunately this is not true. Almost every day we are faced with basic math problems, including percentages. If you are trying to calculate your margin as a retailer or know how many percentages of VAT you pay, we need to manage the percentage every day! Calculating percentages is an important task in everyday math, just like calculating the discount percentage at the mall on "Sale Days".nettilaskin How does percentage work? A percentage expresses a quantitative ratio and performs the same function as fractions. For example, half means 50 percent and 25 percent quarterly. Percentages can also reveal better proportions. For example, 63% means 63/100 of the original value. The percentage, the new value and the original value are the middle numbers of the percentage equation. The percentage is calculated by dividing the new value by the original value and multiplying by 100%. The percentage value or new value is calculated by multiplying the original value by the percentage level and dividing by 100 percent. The original value is calculated by dividing the amount already paid by the percentage and multiplying the result by 100. Where does the idea of "percentage" come from? Originally, the term "percentage" came from the merchants of ancient Babylon. Interest rates are particularly described using fractions and percentages. This term appeared for the first time in Germany in the fifth century, although in Italian "cento" ("percent"). The % symbol will only appear later. In the 19th century, the line of the % sign was not diagonal.
