# How to Multiply Fractions With Mixed Numbers ••• Jose Luis Pelaez Inc../Blend Images/Getty Images

Before multiplying fractions, you convert any mixed numbers to improper fractions. You then multiply all the fractions in your problem, simplify if possible and finally convert back into mixed number form.

## Convert Mixed to Improper

To convert a mixed number to an improper fraction, multiply the denominator by the whole number and add the numerator. For example, in the fraction 5 3/8, multiply the denominator 8 and the whole number 5, then add the numerator 3:

(8 x 5) + 3 = 43

The answer becomes your new numerator. The denominator stays the same. In the example, the improper fraction is 43/8. Repeat this process for all mixed numbers in your equation.

## Multiply the Fractions

Once you've converted all fractions to improper fraction form, multiply the fractions as you would in any fraction multiplication problem. First, multiply all the numerators. Then multiply all the denominators. Write the answers in fraction form with the numerator product on top and the denominator product on bottom. For the problem 10/3 x 3/4, multiply 10 and 3 to find the numerator of 30. Multiply 3 and 4 to find the denominator of 12. Your answer is 30/12.
