2. Fractionation - Wikipedia

   en.wikipedia.org/wiki/Fractionation

   [1] [2] Fractions are collected based on differences in a specific property of the individual components. A common trait in fractionations is the need to find an optimum between the amount of fractions collected and the desired purity in each fraction. Fractionation makes it possible to isolate more than two components in a mixture in a single run.

3. Fraction (chemistry) - Wikipedia

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

   A fraction in chemistry is a quantity collected from a batch of a substance in a fractionating separation process. In such a process, a mixture is separated into fractions, which have compositions that vary according to a gradient. A fraction can be defined as a group of chemicals that have similar boiling points.

4. Fraction - Wikipedia

   en.wikipedia.org/wiki/Fraction

   Common fractions are used most often when the denominator is relatively small. By mental calculation, it is easier to multiply 16 by 3/16 than to do the same calculation using the fraction's decimal equivalent (0.1875). And it is more accurate to multiply 15 by 1/3, for example, than it is to multiply 15 by any decimal approximation of one ...

5. Partial fraction decomposition - Wikipedia

   en.wikipedia.org/wiki/Partial_fraction_decomposition

   Using the preceding decomposition inductively one gets fractions of the form , with ⁡ < ⁡ = ⁡, where G is an irreducible polynomial. If k > 1 , one can decompose further, by using that an irreducible polynomial is a square-free polynomial , that is, 1 {\displaystyle 1} is a greatest common divisor of the polynomial and its derivative .

6. 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 ...

7. Portal:Arithmetic - Wikipedia

   en.wikipedia.org/wiki/Portal:Arithmetic

   It has two definitions: either the integer part of a division (in the case of Euclidean division) or a fraction or ratio (in the case of a general division). For example, when dividing 20 (the dividend ) by 3 (the divisor ), the quotient is 6 (with a remainder of 2) in the first sense and 6 2 3 = 6.66... {\displaystyle 6{\tfrac {2}{3}}=6.66 ...

8. Division (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Division_(mathematics)

   This is denoted as 20 / 5 = 4, or ⁠ 20 / 5 ⁠ = 4. [2] In the example, 20 is the dividend, 5 is the divisor, and 4 is the quotient. Unlike the other basic operations, when dividing natural numbers there is sometimes a remainder that will not go evenly into the dividend; for example, 10 / 3 leaves a remainder of 1, as 10 is not a multiple of 3.

9. Conversion (chemistry) - Wikipedia

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

   Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
