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. Clearing denominators - Wikipedia

   en.wikipedia.org/wiki/Clearing_denominators

   The first step is to determine a common denominator D of these fractions – preferably the least common denominator, which is the least common multiple of the Q i. This means that each Q i is a factor of D, so D = R i Q i for some expression R i that is not a fraction. Then

4. Irreducible fraction - Wikipedia

   en.wikipedia.org/wiki/Irreducible_fraction

   The irreducible fraction for a given element is unique up to multiplication of denominator and numerator by the same invertible element. In the case of the rational numbers this means that any number has two irreducible fractions, related by a change of sign of both numerator and denominator; this ambiguity can be removed by requiring the ...

5. Lowest common denominator - Wikipedia

   en.wikipedia.org/wiki/Lowest_common_denominator

   In mathematics, the lowest common denominator or least common denominator (abbreviated LCD) is the lowest common multiple of the denominators of a set of fractions. It simplifies adding, subtracting, and comparing fractions.

   en.wikipedia.org/wiki/Portal:Arithmetic

   A common, vulgar, or simple fraction (examples: and ) consists of an integer numerator, displayed above a line (or before a slash like 1 ⁄ 2), and a non-zero integer denominator, displayed below (or after) that line. If these integers are positive, then the numerator represents a number of equal parts, and the denominator indicates how many ...

8. Subtraction - Wikipedia

   en.wikipedia.org/wiki/Subtraction

   While primarily associated with natural numbers in arithmetic, subtraction can also represent removing or decreasing physical and abstract quantities using different kinds of objects including negative numbers, fractions, irrational numbers, vectors, decimals, functions, and matrices. [2] In a sense, subtraction is the inverse of addition.
