A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a/b or , where a and b are both integers. [9] As with other fractions, the denominator (b) cannot be zero. Examples include 1 / 2 , − 8 / 5 , −8 / 5 , and 8 / −5
The original fraction could have also been reduced in a single step by using the greatest common divisor of 90 and 120, which is 30. As 120 ÷ 30 = 4, and 90 ÷ 30 = 3, one gets = Which method is faster "by hand" depends on the fraction and the ease with which common factors are spotted.
The solar savings fraction of a particular system is dependent on many factors such as the load, the collection and storage sizes, the operation, and the climate. As an example, the same solar-thermal water heating system installed in a single-family house in Arizona might have f=0.75 (75%), while in a much colder and cloudier climate, like ...
A related quantity is the percentile rank of a score, expressed in percent, which represents the fraction of scores in its distribution that are less than it, an exclusive definition. Percentile scores and percentile ranks are often used in the reporting of test scores from norm-referenced tests , but, as just noted, they are not the same.
The "population-attributable fraction" (PAF)—that is, the share of cancer deaths that could be prevented if a given risk factor were removed—is 28.5 percent for cigarette smoking and 0.7 ...
Preventable fraction among the unexposed: PFu (CER − EER) / CER: 0.75 Odds ratio: OR (EE / EN) / (CE / CN) 0.167 Risk increase. Example of risk increase Quantity
In mathematics, "rational" is often used as a noun abbreviating "rational number". The adjective rational sometimes means that the coefficients are rational numbers. For example, a rational point is a point with rational coordinates (i.e., a point whose coordinates are rational numbers); a rational matrix is a matrix of rational numbers; a rational polynomial may be a polynomial with rational ...
A simple or regular continued fraction is a continued fraction with numerators all equal one, and denominators built from a sequence {} of integer numbers. The sequence can be finite or infinite, resulting in a finite (or terminated ) continued fraction like
