A percentage is an amount or a given part in every hundred, and percentages are the fraction with 100 as a denominator. The term 'percentage' has been derived from the Latin word 'per centum,' which means 'by the hundred.' Percentages can be calculated using two ways, i.e., by changing the fraction's denominator to 100 or by the unitary method. The symbol used to represent percentage is '%.'
While calculating percentages using mental math, there are specific steps to keep in mind.
