An increase of $0.15 on a price of $2.50 is an increase by a fraction of 0.15 / 2.50 = 0.06. Expressed as a percentage, this is a 6% increase. While many percentage values are between 0 and 100, there is no mathematical restriction and percentages may take on other values. [4]
The percent sign % (sometimes per cent sign in British English) is the symbol used to indicate a percentage, a number or ratio as a fraction of 100. Related signs include the permille (per thousand) sign ‰ and the permyriad (per ten thousand) sign ‱ (also known as a basis point), which indicate that a number is divided by one thousand or ten thousand, respectively.
[18] [19] This quantity has also been referred to as a log percentage and denoted L%. [2] Since the derivative of the natural log at 1 is 1, log points are approximately equal to percent change for small differences – for example an increase of 1% equals an increase of 0.995 cNp, and a 5% increase gives a 4.88 cNp increase.
A positive or negative number when divided by zero is a fraction with the zero as denominator. Zero divided by a negative or positive number is either zero or is expressed as a fraction with zero as numerator and the finite quantity as denominator. Zero divided by zero is zero.

Rather they refer to what percentage of the total weight is milk fat. For example, one cup of milk weighs about 225 grams. Of that weight, 2% milk holds 5 grams of fat and whole milk contains 8 grams.
Percentages greater than 100 or less than zero are treated in the same way, e.g. 311% equals 311/100, and −27% equals −27/100. The related concept of permille or parts per thousand (ppt) has an implied denominator of 1000, while the more general parts-per notation , as in 75 parts per million (ppm), means that the proportion is 75/1,000,000.
Contrary to popular belief, they don't mean that all but 1 percent or 2 percent of the fat has been removed. What the '2 percent' actually means in 2 percent milk — and why the name whole milk ...
It is important to specify which method is used when referring to a retailer's profit as a percentage. Some retailers use margins because profits are easily calculated from the total of sales. If margin is 30%, then 30% of the total of sales is the profit. If markup is 30%, the percentage of daily sales that are profit will not be the same ...
