Comparing fractions with the same positive denominator yields the same result as comparing the numerators: > because 3 > 2, and the equal denominators are positive. If the equal denominators are negative, then the opposite result of comparing the numerators holds for the fractions:
Two fractions a / b and c / d are equal or equivalent if and only if ad = bc.) For example, 1 / 4 , 5 / 6 , and −101 / 100 are all irreducible fractions. On the other hand, 2 / 4 is reducible since it is equal in value to 1 / 2 , and the numerator of 1 / 2 is less than the numerator ...
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 ...
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 ...
Placard outside a shop in Bordeaux advertising subtraction of 20% from the price of the second perfume purchased. Subtraction (which is signified by the minus sign −) is one of the four arithmetic operations along with addition, multiplication and division. Subtraction is an operation that represents removal of objects from a collection. [1]

The number of Farey fractions with denominators equal to k in F n is given by φ(k) when k ≤ n and zero otherwise. Concerning the numerators one can define the function () that returns the number of Farey fractions with numerators equal to h in F n. This function has some interesting properties as [6]
