2. Clearing denominators - Wikipedia

   en.wikipedia.org/wiki/Clearing_denominators

   The smallest common multiple of the two denominators 6 and 15z is 30z, so one multiplies both sides by 30z: 5 x z + 2 y = 30 z . {\displaystyle 5xz+2y=30z.\,} The result is an equation with no fractions.

3. Lowest common denominator - Wikipedia

   en.wikipedia.org/wiki/Lowest_common_denominator

   It is usually easiest to add, subtract, or compare fractions when each is expressed with the same denominator, called a "common denominator". For example, the numerators of fractions with common denominators can simply be added, such that + = and that <, since each fraction has the common denominator 12.

   en.wikipedia.org/wiki/Fraction

   As with other fractions, the denominator (b) cannot be zero. Examples include ⁠ 1 / 2 ⁠, − ⁠ 8 / 5 ⁠, ⁠ −8 / 5 ⁠, and ⁠ 8 / −5 ⁠. The term was originally used to distinguish this type of fraction from the sexagesimal fraction used in astronomy. [10] Common fractions can be positive or negative, and they can be proper or ...

5. Heaviside cover-up method - Wikipedia

   en.wikipedia.org/wiki/Heaviside_cover-up_method

   We calculate each respective numerator by (1) taking the root of the denominator (i.e. the value of x that makes the denominator zero) and (2) then substituting this root into the original expression but ignoring the corresponding factor in the denominator. Each root for the variable is the value which would give an undefined value to the ...

6. Least common multiple - Wikipedia

   en.wikipedia.org/wiki/Least_common_multiple

   The least common multiple of the denominators of two fractions is the "lowest common denominator" (lcd), and can be used for adding, subtracting or comparing the fractions. The least common multiple of more than two integers a , b , c , . . . , usually denoted by lcm( a , b , c , . . .) , is defined as the smallest positive integer that is ...
