$Multiplying Mixed Numbers | MathHelp.com Need a custom math course? Visit https://www.MathHelp.com. This lesson covers multiplying mixed numbers. Students learn to multiply mixed numbers by first rewriting the mixed numbers as improper fractions, then multiplying the improper fractions together, then rewriting the resulting improper fraction as a mixed number, if necessary. For example, to multiply 1 8/15 x 1 1/4, first rewrite the mixed numbers as improper fractions, to get 23/15 x 5/4. Next, cross-cancel the 15 and 5 to 3 and 1, and we have 23/3 x 1/4. Next, multiply across the numerators and denominators to get 23/12. Finally, rewrite 23/12 as the mixed number 1 11/12.$

$Rational Equations | MathHelp.com Need a custom math course? Visit https://www.MathHelp.com. This lesson covers rational equations. Students learn that when solving rational equations, the first step is to factor each of the denominators, if possible, then multiply both sides of the equation by the common denominator for all the fractions in order to get rid of the fractions, and solve from here. Finally, check each solution to see if it makes a denominator in the original equation equal to zero. If so, then it cannot be a solution to the equation.$
