  2. Irreducible fraction - Wikipedia

    en.wikipedia.org/wiki/Irreducible_fraction

    Irreducible fraction. An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) is a fraction in which the numerator and denominator are integers that have no other common divisors than 1 (and −1, when negative numbers are considered). [1] In other words, a fraction ⁠a b⁠ is irreducible if and only if a and ...

    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 ⁠12⁠, − ⁠85⁠, ⁠−85⁠, and ⁠8−5⁠.

    en.wikipedia.org/wiki/24-form_tai_chi

    The form was the result of an effort by the Chinese Sports Committee, which, in 1956, brought together four tai chi teachers—Chu Guiting, Cai Longyun, Fu Zhongwen, and Zhang Yu—to create a simplified form of tai chi as exercise for the masses. Some sources suggests that the form was structured in 1956 by master Li Tianji (李天骥).

    The 14 simplified components in Chart 2 are never used alone as individual characters. They only serve as components. Example of derived simplification based on the component 𦥯, simplified to 𰃮 (), include: 學 → 学; 覺 → 觉; 黌 → 黉. Chart 1 collects 352 simplified characters that generally cannot be used as components.

    This image actually shows two Karnaugh maps: for the function ƒ, using minterms (colored rectangles) and for its complement, using maxterms (gray rectangles). In the image, E () signifies a sum of minterms, denoted in the article as . The Karnaugh map (KM or K-map) is a method of simplifying Boolean algebra expressions.

  9. Ratio - Wikipedia

    en.wikipedia.org/wiki/Ratio

    As for fractions, the simplest form is considered that in which the numbers in the ratio are the smallest possible integers. Thus, the ratio 40:60 is equivalent in meaning to the ratio 2:3, the latter being obtained from the former by dividing both quantities by 20. Mathematically, we write 40:60 = 2:3, or equivalently 40:60∷2:3.
