  2. Irreducible fraction - Wikipedia

    en.wikipedia.org/wiki/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]

  4. Percentage - Wikipedia

    en.wikipedia.org/wiki/Percentage

    • One formula for all tasks: Advantages: • Without a formula • Easy to change over if the size you are looking for – here G – is in the top left of the counter. Advantages: • Without a formula • Simple rule of three – here as a chain of equations • Application for mental arithmetic

  5. Lever rule - Wikipedia

    en.wikipedia.org/wiki/Lever_rule

    In chemistry, the lever rule is a formula used to determine the mole fraction (x i) or the mass fraction (w i) of each phase of a binary equilibrium phase diagram.It can be used to determine the fraction of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus line.

  6. Kelly criterion - Wikipedia

    en.wikipedia.org/wiki/Kelly_criterion

    Example of the optimal Kelly betting fraction, versus expected return of other fractional bets. In probability theory, the Kelly criterion (or Kelly strategy or Kelly bet) is a formula for sizing a sequence of bets by maximizing the long-term expected value of the logarithm of wealth, which is equivalent to maximizing the long-term expected geometric growth rate.

  7. Mass fraction (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Mass_fraction_(chemistry)

    It is one way of expressing the composition of a mixture in a dimensionless size; mole fraction (percentage by moles, mol%) and volume fraction (percentage by volume, vol%) are others. When the prevalences of interest are those of individual chemical elements , rather than of compounds or other substances, the term mass fraction can also refer ...

  8. Volume fraction - Wikipedia

    en.wikipedia.org/wiki/Volume_fraction

    Volume percent is the concentration of a certain solute, measured by volume, in a solution.It has as a denominator the volume of the mixture itself, as usual for expressions of concentration, [2] rather than the total of all the individual components’ volumes prior to mixing:

  9. Parkland formula - Wikipedia

    en.wikipedia.org/wiki/Parkland_formula

    where mass (m) is in kilograms (kg), burned area (A) as a fraction of total body surface area, and volume (V) is in milliliters (mL). For example, a person weighing 75 kg with burns to 20% of his or her body surface area would require 4 x 75 x 20 = 6,000 mL of fluid replacement within 24 hours.
