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 .
One half is a rational number that lies midway between nil and unity (which are the elementary additive and multiplicative identities) as the quotient of the first two non-zero integers, . It has two different decimal representations in base ten, the familiar and the recurring , with a similar pair of expansions in any even base; while in odd ...
Lucas numbers have L 1 = 1, L 2 = 3, and L n = L n−1 + L n−2. Primefree sequences use the Fibonacci recursion with other starting points to generate sequences in which all numbers are composite. Letting a number be a linear function (other than the sum) of the 2 preceding numbers. The Pell numbers have P n = 2P n−1 + P n−2.

It is equal to the frequency ratio (1.5) 12 ⁄ 2 7 = 531441 ⁄ 524288 ≈ 1.01364, or about 23.46 cents, roughly a quarter of a semitone (in between 75:74 and 74:73 [2]). The comma that musical temperaments often "temper" is the Pythagorean comma.
A fraction 3 / y requires three terms in its greedy expansion if and only if y ≡ 1 (mod 6), for then −y mod x = 2 and y(y + 2) / 3 is odd, so the fraction remaining after a single step of the greedy expansion, () ⌈ ⌉ = (+) is in simplest terms. The simplest fraction 3 / y with a three-term expansion is 3 / 7 .
