How To: Add fractions with like and unlike denominators

This video shows a tutorial of adding fractions. The first example shows a fraction that has like denominators so all you had to do is add the denominators. In the second example it shows two fractions that do not have like denominators. Therefore, you need to find the greatest common factor among the two denominators. Once this is found, you multiply the fraction on both the numerator and denominator to make both of the fractions match. Then all that is left is to add the numerators to finish the addition of the fractions.
