Adding fractions with like denominators
In this section, we will add fractions with like denominators using addition statements. When adding fractions with like denominators, the numerators are added together to get the sum of the parts; however, the denominators stay the same. We will write our answers in lowest terms by first finding the greatest common factor (GCF) of both the numerator and denominator and then dividing the numerator and denominator by this GCF. Finally, we will solve word problems involving the addition of fractions with like denominators. We will make these word problems easier to visualize by incorporating diagrams.
