What Are Percentages?
Dealing with fractions can be difficult when you are performing mathematical operations in your daily lives. And percentages are another form of fraction; which causes havoc in the minds of the students. For instance, if you run a store, and you are telling the suppliers that 4/5th of your inventory is finished. He will most probably don’t understand you. Or you want to tell your customers that they get a 1/3rd discount on their entire purchase because of Christmas, they wouldn’t be using calculators at your store. Thus, comes the concept of percentage. It provides another way of representing factions and decimals. It just means per hundred. So, if you get 50%, that means 50 per hundred or half. A definite upgrade to the complicated decimal or fraction representation.
