WHAT DOES PERCENTAGE TELL YOU?
Percentage is commonly used to represent statistical data; it is considered an important tool to illustrate the proportion of something. The percentage total of a data set should always add up to 100 except in special circumstances. Percentages larger than the value of 100 often occur in financial situations, say for instance if a item originally costing $1 was sold for $1 then the profit would be 0%, if the same item was sold for $2 then the profit would be 100%, and selling it for $3 would be a 200% profit.
