A percentage by itself represents just a fraction of a whole. When a percentage amount is multiplied to another number, the operation produces a value that equals the given percent of the original number. When the percentage amount is less than a hundred, the product will be a reduction of the original number, and if the percentage amount is greater than one hundred, the product will then be greater than the number. Multiplying a number by 100 percent is a just variation of the multiplicative identity and will result in the value being unchanged. The multiplication process of a percentage to a number follows normal arithmetic rules, with the addition of division at the end.
Obtain a desired number and percentage amount for example purposes. In this example, let the number by 700 and the percentage amount be 60 percent.
Multiply the percentage amount to the number. In this example, multiplying 60 to 700 results in 42,000.
Divide the product of the number and percent by 100. For this example, division of 100 into 42,000 results in 420.
