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. Addition - Wikipedia

   en.wikipedia.org/wiki/Addition

   Addition of fractions is much simpler when the denominators are the same; in this case, one can simply add the numerators while leaving the denominator the same: + = +, so + = + =. [ 63 ] The commutativity and associativity of rational addition is an easy consequence of the laws of integer arithmetic. [ 64 ]

4. Arithmetic - Wikipedia

   en.wikipedia.org/wiki/Arithmetic

   A similar procedure is used for subtraction. If the two numbers do not have the same denominator then they must be transformed to find a common denominator. This can be achieved by scaling the first number with the denominator of the second number while scaling the second number with the denominator of the first number.

5. Mediant (mathematics) - Wikipedia

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

   However, if the fraction 1/1 is replaced by the fraction 2/2, which is an equivalent fraction denoting the same rational number 1, the mediant of the fractions 2/2 and 1/2 is 3/4. For a stronger connection to rational numbers the fractions may be required to be reduced to lowest terms , thereby selecting unique representatives from the ...

6. Fraction - Wikipedia

   en.wikipedia.org/wiki/Fraction

   Dividing the numerator and denominator of a fraction by the same non-zero number yields an equivalent fraction: if the numerator and the denominator of a fraction are both divisible by a number (called a factor) greater than 1, then the fraction can be reduced to an equivalent fraction with a smaller numerator and a smaller denominator.

7. Krypto (game) - Wikipedia

   en.wikipedia.org/wiki/Krypto_(game)

   The official international rules for Krypto differ slightly from the house rules, and they involve a system of scorekeeping. Five cards are dealt face up in the center of the game table. (Each player works with the same set of five cards, rather than a set exclusi

   High school football enthusiasts who want to place a bet on a big game have no choice but to turn to an offshore site. Accepting a wager on high school sports is outlawed in Nevada and other U.S ...

9. 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 ...
