  2. Continued fraction (generalized) - Wikipedia

    en.wikipedia.org/wiki/Continued_fraction...

    Note: this continued fraction's rate of convergence μ tends to 3 − √ 8 ≈ 0.1715729, hence ⁠ 1 / μ ⁠ tends to 3 + √ 8 ≈ 5.828427, whose common logarithm is 0.7655... ≈ ⁠ 13 / 17 ⁠ > ⁠ 3 / 4 ⁠. The same ⁠ 1 / μ ⁠ = 3 + √ 8 (the silver ratio squared) also is observed in the unfolded general continued fractions of ...

    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 ⁠.

  4. Multiplicative inverse - Wikipedia

    en.wikipedia.org/wiki/Multiplicative_inverse

    In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/ x or x1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a / b is b / a. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one ...

    For instance, the primary pseudoperfect number 1806 is the product of the prime numbers 2, 3, 7, and 43, and gives rise to the Egyptian fraction 1 = ⁠ 1 / 2 ⁠ + ⁠ 1 / 3 ⁠ + ⁠ 1 / 7 ⁠ + ⁠ 1 / 43 ⁠ + ⁠ 1 / 1806 ⁠.

  6. Partial fraction decomposition - Wikipedia

    en.wikipedia.org/wiki/Partial_fraction_decomposition

    The concept was discovered independently in 1702 by both Johann Bernoulli and Gottfried Leibniz. [3] In symbols, the partial fraction decomposition of a rational fraction of the form where f and g are polynomials, is the expression of the rational fraction as. {\displaystyle {\frac {f (x)} {g (x)}}=p (x)+\sum _ {j} {\frac {f_ {j} (x)} {g_ {j ...

  7. Unit fraction - Wikipedia

    en.wikipedia.org/wiki/Unit_fraction

    Slices of approximately 1/8 of a pizza. A unit fraction is a positive fraction with one as its numerator, 1/ n.It is the multiplicative inverse (reciprocal) of the denominator of the fraction, which must be a positive natural number.

  8. Continued fraction - Wikipedia

    en.wikipedia.org/wiki/Continued_fraction

    If x is rational, it will have two continued fraction representations that are finite, x 1 and x 2, and similarly a rational y will have two representations, y 1 and y 2. The coefficients beyond the last in any of these representations should be interpreted as +∞; and the best rational will be one of z(x 1, y 1), z(x 1, y 2), z(x 2, y 1), or ...

  9. Number Forms - Wikipedia

    en.wikipedia.org/wiki/Number_Forms

    Number Forms is a Unicode block containing Unicode compatibility characters that have specific meaning as numbers, but are constructed from other characters. They consist primarily of vulgar fractions and Roman numerals. In addition to the characters in the Number Forms block, three fractions (¼, ½, and ¾) were inherited from ISO-8859-1 ...
