2. Rate (mathematics) - Wikipedia

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

   In mathematics, a rate is the quotient of two quantities, often represented as a fraction. [1] If the divisor (or fraction denominator) in the rate is equal to one expressed as a single unit, and if it is assumed that this quantity can be changed systematically (i.e., is an independent variable), then the dividend (the fraction numerator) of the rate expresses the corresponding rate of change ...

3. Conversion of units - Wikipedia

   en.wikipedia.org/wiki/Conversion_of_units

   Find facts relating the original unit to the desired unit: 1 mile = 5280 feet and 1 hour = 3600 seconds; Next use the above equations to construct a fraction that has a value of unity and that contains units such that, when it is multiplied with the original physical value, will cancel the original units:

4. 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.

5. Solving quadratic equations with continued fractions - Wikipedia

   en.wikipedia.org/wiki/Solving_quadratic...

   The rate of convergence depends on the absolute value of the ratio between the two roots: the farther that ratio is from unity, the more quickly the continued fraction converges. When the monic quadratic equation with real coefficients is of the form x 2 = c , the general solution described above is useless because division by zero is not well ...

6. Egyptian fraction - Wikipedia

   en.wikipedia.org/wiki/Egyptian_fraction

   Egyptian fractions can provide a solution to rope-burning puzzles, in which a given duration is to be measured by igniting non-uniform ropes which burn out after a unit time. Any rational fraction of a unit of time can be measured by expanding the fraction into a sum of unit fractions and then, for each unit fraction /, burning a rope so that ...

7. Molar volume - Wikipedia

   en.wikipedia.org/wiki/Molar_volume

   The interest stems from that accurate measurements of the unit cell volume, atomic weight and mass density of a pure crystalline solid provide a direct determination of the Avogadro constant. [3] The CODATA recommended value for the molar volume of silicon is 1.205 883 199 (60) × 10 −5 m 3 ⋅mol −1, with a relative standard uncertainty of ...
