Subdivisions of an inch are typically written using dyadic fractions with odd number numerators; for example, two and three-eighths of an inch would be written as 2 + 3 / 8 ″ and not as 2.375″ nor as 2 + 6 / 16 ″. However, for engineering purposes fractions are commonly given to three or four places of decimals and have been ...
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

a fraction with A as numerator and B as denominator that represents the quotient (i.e., A divided by B, or). This can be expressed as a simple or a decimal fraction, or as a percentage, etc. [7] When a ratio is written in the form A:B, the two-dot character is sometimes the colon punctuation mark. [8]

In the following quote, an "apertal ratio" of "1 ⁄ 24" is calculated as the ratio of 6 inches (150 mm) to 1 ⁄ 4 inch (6.4 mm), corresponding to an f /24 f-stop: In every lens there is, corresponding to a given apertal ratio (that is, the ratio of the diameter of the stop to the focal length), a certain distance of a near object from it ...
(5:4 works out to root(25+16), or 6.403 for the diagonal - divide by that then multiply by 5 or 4. 4:3 is the simple one, as the diagonal is 5 (hopefully familiar from school?). 16:10 gives 18.868, and 16:9, via root(256+81), produces 18.358 - or in other words, in the 16:10 case, a 19" diagonal screen with a resolution of 1440x900, like what I ...
