ByAdding Fraction With Different Denominator. Definition. Common Denominator – When the fractions in an addition problem do not have the same denominators, rewrite the problem so that each fraction has the same denominator.

ByAdding Fractions With Like and Unlike Denominators. Presented By Nathaniel Thompson. What is a fraction?. A fraction is a representation of a part of a whole unit. A fraction has two parts, a numerator and a denominator. 2 3. The top number (2) is called the numerator.
