The lowest common denominator of a set of fractions is the lowest number that is a multiple of all the denominators: their lowest common multiple. When the denominators of two or more fractions are the same, they are Common Denominators. In some problems it is required to evaluate algebraic expressions. The product of the denominators is always a common denominator, as in: We explain what the denominator of a fraction is and give examples of how the concept is taught in primary-school maths, as well as explaining fractions equivalence and the relationship between the numerator and denominator. and get FREE worksheets, activities & offers from TheSchoolRun.com, Compare and order fractions with the same denominators, Different denominators: fractions addition.
