For a complete lesson on adding mixed numbers go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson students learn to add mixed numbers by first adding the fractions then adding the whole numbers. For example to add 4 2/5 + 7 4/5 first add 2/5 + 4/5 to get 6/5 then add 4 + 7 to get 11. So 4 2/5 + 7 4/5 = 11 6/5. Notice however that the answer 11 6/5 contains an improper fraction 6/5 which is the same as 1 1/5 so 11 6/5 can be rewritten as 11 + 1 1/5 which simplifies to 12 1/5. So 4 2/5 + 7 4/5 = 12 1/5. Note that some of the problems in this lesson also require the student to find a common denominator for the fractions. For example 5 1/4 + 6 3/8.
