Percentage is a ratio or number expressed as “a part of 100”. The word “percent” actually means “per 100”. Percentage is generally shown using the % sign. which is a diagonal line with a circle on each side. Percentages can be easily converted to fractions and decimals. They are used to show how large or small an amount is compared to another amount. Percentages usually only have values between 0 and 100 but in certain cases these values can exceed one hundred. 100% stands for 1/1 = 1 =1:1, so it is the exact proportion or full amount of the value that the percentage originally belonged to.Where do we use Percentages?Percentage are not only commonly used in the classroom but also in our everyday life.
