2. Fraction - Wikipedia

   en.wikipedia.org/wiki/Fraction

   The process for subtracting fractions is, in essence, the same as that of adding them: find a common denominator, and change each fraction to an equivalent fraction with the chosen common denominator. The resulting fraction will have that denominator, and its numerator will be the result of subtracting the numerators of the original fractions.

3. Equivalent (chemistry) - Wikipedia

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

   An equivalent (symbol: officially equiv; [1] unofficially but often Eq [2]) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. It is an archaic quantity that was used in chemistry and the biological sciences (see Equivalent weight § In ...

4. Mole fraction - Wikipedia

   en.wikipedia.org/wiki/Mole_fraction

   Mole fraction is numerically identical to the number fraction, which is defined as the number of particles of a constituent N i divided by the total number of all molecules N tot. Whereas mole fraction is a ratio of amounts to amounts (in units of moles per moles), molar concentration is a quotient of amount to volume (in units of moles per litre).

5. Irreducible fraction - Wikipedia

   en.wikipedia.org/wiki/Irreducible_fraction

   An equivalent definition is sometimes useful: if a and b are integers, then the fraction ⁠ a / b ⁠ is irreducible if and only if there is no other equal fraction ⁠ c / d ⁠ such that | c | < | a | or | d | < | b |, where | a | means the absolute value of a. [4] (Two fractions ⁠ a / b ⁠ and ⁠ c / d ⁠ are equal or equivalent if and ...

6. Repeating decimal - Wikipedia

   en.wikipedia.org/wiki/Repeating_decimal

   Conversely the period of the repeating decimal of a fraction ⁠ c / d ⁠ will be (at most) the smallest number n such that 10 n − 1 is divisible by d. For example, the fraction ⁠ 2 / 7 ⁠ has d = 7, and the smallest k that makes 10 k − 1 divisible by 7 is k = 6, because 999999 = 7 × 142857. The period of the fraction ⁠ 2 / 7 ⁠ is ...

8. Unit fraction - Wikipedia

   en.wikipedia.org/wiki/Unit_fraction

   In modular arithmetic, unit fractions can be converted into equivalent whole numbers, allowing modular division to be transformed into multiplication. Every rational number can be represented as a sum of distinct unit fractions; these representations are called Egyptian fractions based on their use in ancient Egyptian mathematics. Many infinite ...
