  2. Irreducible fraction - Wikipedia

    en.wikipedia.org/wiki/Irreducible_fraction

    A fraction that is reducible can be reduced by dividing both the numerator and denominator by a common factor. It can be fully reduced to lowest terms if both are divided by their greatest common divisor. [5] In order to find the greatest common divisor, the Euclidean algorithm or prime factorization can be used. The Euclidean algorithm is ...

  3. Lagrange number - Wikipedia

    en.wikipedia.org/wiki/Lagrange_number

    If we don't allow √ 2 then we can increase the number on the right hand side of the inequality from 2 √ 2 to √ 221 /5. Repeating this process we get an infinite sequence of numbers √ 5, 2 √ 2, √ 221 /5, ... which converge to 3. [1] These numbers are called the Lagrange numbers, [2] and are named after Joseph Louis Lagrange.

    [14] Note that the gross score in 'world handicap system' is calculated as the number of strokes taken for a hole + the handicap allowance for that hole . The adjusted gross score in 'world handicap system' is the gross score adjusted such that the maximum on any particular hole is the number of strokes taken for a hole + the handicap allowance ...

  6. Ratio - Wikipedia

    en.wikipedia.org/wiki/Ratio

    For example, a ratio of 3:2 is the same as 12:8. It is usual either to reduce terms to the lowest common denominator, or to express them in parts per hundred . If a mixture contains substances A, B, C and D in the ratio 5:9:4:2 then there are 5 parts of A for every 9 parts of B, 4 parts of C and 2 parts of D.

  7. Simple continued fraction - Wikipedia

    en.wikipedia.org/wiki/Simple_continued_fraction

    Other numbers like e have only small terms early in their continued fraction, which makes them more difficult to approximate rationally. The golden ratio Φ has terms equal to 1 everywhere—the smallest values possible—which makes Φ the most difficult number to approximate rationally. In this sense, therefore, it is the "most irrational" of ...

  8. Rational number - Wikipedia

    en.wikipedia.org/wiki/Rational_number

    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 ...

  9. 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.
