In mathematics, a percentage is a way of expressing a number as a fraction of 100 ( %, which means is for every 100 do ).?? It is often denoted using the percentage %, which must be written immediately after the number to which refers, without space separation.[1] For example: " thirty-two percent " It is represented by 32% and mean ' thirty-two of every hundred '.The % symbol is a stylized form of the two zeros. It evolved from a similar symbol only that he had a horizontal line instead of diagonal ( c. 1650 ) that in turn comes from a symbol representing "P cento " ( c. 1425 ).The percentage is somewhat per cent ( 100 units ) for which concludes that it is an amount which corresponds proportionally to a part of one hundred. ¿
