Dealing with fractions can be difficult when you are performing mathematical operations in your daily lives. 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.
A percentage is value that tells you how much of a whole you have. Percentages are expressed as ratios with one hundred being the denominator. Something to always keep in mind is that percentages are relative in their size and value. If you own 1% of $500 piece of fitness equipment, that's not a lot ($5 to be exact). If you own 1% of Apple Computers (worth over one-trillion dollars), that's a whole different level. These worksheets explain how to convert between percentages, fractions, and decimals. Students will also rewrite word problems to calculate the actual value of a given percentage.
