Dividing Mixed Numbers - YourTeacher.com - Pre Algebra Help

For a complete lesson on dividing 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 divide mixed numbers by first rewriting the mixed numbers as improper fractions, then dividing the improper fractions, then rewriting the resulting improper fraction as a mixed number, if necessary. For example, to simplify 3 1/3 1 4/7, first rewrite the mixed numbers as improper fractions, to get 10/3 11/7. Next, change the division sign to multiplication and flip the second fraction, to get 10/3 x 7/11. Next, multiply across the numerators and denominators to get 70/33. Finally, rewrite 70/33 as the mixed number 2 4/33.
