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 ...
Number Munchers is the first educational game in the Munchers series. Designed to teach basic math skills, it was popular among American school children in the 1980s and 1990s and was the recipient of several awards. [2] An updated 3D version, Math Munchers Deluxe, was released in 1995. [3]
The game was designed for school and home use for grades four to eight with parental controlled options to set the difficulty level. [5] It teaches multiples, factors, prime numbers, equalities, and inequalities. It helped introduce math skills to younger students, [6] while helping older students to reinforce their existing math skills. [7]
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 divisible by ...
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.

In mathematics, the Farey sequence of order n is the sequence of completely reduced fractions, either between 0 and 1, or without this restriction, [a] which when in lowest terms have denominators less than or equal to n, arranged in order of increasing size.
