What is percentage ?

• The term "percent" comes from the Latin word "per centum" which means "hundreds". Percentages are fractions with 100 as the denominator.
• In other words, it is the relationship between the part and the whole that makes the whole value  always  100.A percentage is a fraction or  ratio whose overall value  is always 100.
• For example, if Sam got his 30% on a math test, it means  he got 30  out of his 100. This is written in fractional form as 30/100, where 30 looks like this:100 in relation.
• A percentage is defined as a specific part or amount of 100. A fraction with a denominator of 100, represented by the "%" symbol.
