2. Lowest common denominator - Wikipedia

   en.wikipedia.org/wiki/Lowest_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. Without computing a common denominator, it is not obvious as to what 5 12 + 11 18 {\displaystyle {\frac {5}{12}}+{\frac {11}{18}}} equals, or whether 5 12 {\displaystyle {\frac {5 ...

3. Fraction - Wikipedia

   en.wikipedia.org/wiki/Fraction

   A compound fraction is a fraction of a fraction, or any number of fractions connected with the word of, [22] [23] corresponding to multiplication of fractions. To reduce a compound fraction to a simple fraction, just carry out the multiplication (see § Multiplication ).

4. 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 ...

5. One half - Wikipedia

   en.wikipedia.org/wiki/One_half

   One half is one of the few fractions which are commonly expressed in natural languages by suppletion rather than regular derivation. In English, for example, compare the compound "one half" with other regular formations like "one-sixth". A half can also be said to be one part of something divided into two equal parts.

6. Equating coefficients - Wikipedia

   en.wikipedia.org/wiki/Equating_coefficients

   Example in nested radicals [ edit ] A similar problem, involving equating like terms rather than coefficients of like terms, arises if we wish to de-nest the nested radicals a + b c {\displaystyle {\sqrt {a+b{\sqrt {c}}\ }}} to obtain an equivalent expression not involving a square root of an expression itself involving a square root, we can ...

7. Fraction - en.wikipedia.org

   en.wikipedia.org/.../Fraction_(mathematics)

   A fraction (from Latin: fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how ma

8. Simple continued fraction - Wikipedia

   en.wikipedia.org/wiki/Simple_continued_fraction

   This produces a sequence of approximations, all of which are rational numbers, and these converge to the starting number as a limit. This is the (infinite) continued fraction representation of the number. Examples of continued fraction representations of irrational numbers are: √ 19 = [4;2,1,3,1,2,8,2,1,3,1,2,8,...] (sequence A010124 in the ...

9. 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.
