                                                          For a complete lesson on multiplying 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 multiply mixed numbers by first rewriting the mixed numbers as improper fractions then multiplying the improper fractions together then rewriting the resulting improper fraction as a mixed number if necessary. For example to multiply 1 8/15 x 1 1/4 first rewrite the mixed numbers as improper fractions to get 23/15 x 5/4. Next cross-cancel the 15 and 5 to 3 and 1 and we have 23/3 x 1/4. Next multiply across the numerators and denominators to get 23/12. Finally rewrite 23/12 as the mixed number 1 11/12.
