Lesson Summary:

In this lesson, we learn how to add mixed numbers that have a common denominator, such as 3 and 4/5 plus 6 and 2/5. We can add the whole number parts together and then add the fractional parts together. If we end up with an improper fraction, we can simplify it to a mixed number for our answer. Alternatively, we could change everything to improper fractions and add them together. Either way, we can obtain a correct answer, and we have the flexibility to write our answer as either a mixed number or an improper fraction.
