Irreducible Fraction -- from Wolfram MathWorld

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 of 2 / 4 . See more An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) is a fraction in which the numerator and denominator are integers that have no other common divisors than 1 (and −1, when negative numbers … See more Every rational number has a unique representation as an irreducible fraction with a positive denominator (however 2/3 = −2/−3 although both are irreducible). Uniqueness is a consequence of the unique prime factorization of integers, since a/b = c/d … See more The notion of irreducible fraction generalizes to the field of fractions of any unique factorization domain: any element of such a field can … See more • Weisstein, Eric W.

WebDes fractions comme 2 3, 3 4, 5 13 et 8 19 sont des fractions irréductibles. La fraction 8 18 n’est pas une fraction irréductible, car le nombre 2 est un diviseur entier commun à 8 et 18. Alors, la fraction irréductible équivalente à 8 18 est la fraction 4 9 qui est irréductible. WebUne fraction irréductible est une fraction simplifiée le plus possible. Une fraction est irréductible lorsque son numérateur et son dénominateur sont premiers entre eux. … WebLes fractions ne sont pas oubliées, avec cet exercice sur les fractions 3ème corrigé , les systèmes d'équation non plus avec cet exercice corrigé sur les systèmes d'équation en 3ème .
