# How to Multiply Mixed Numbers

Do you need two and a half dozen cookies, but a recipe only makes one dozen? Don’t let the daunting task of multiplying mixed numbers get in the way.

### Instructions

- Step 1:
**Write the numbers down**Write your mixed numbers down on a piece of paper to convert them to improper fractions. - Step 2:
**Convert to improper fraction**Multiply the denominator – the bottom number of the fraction – by the whole number, and then add the top number of the fraction – the numerator. Write the product on top of the denominator. - TIP: For example, the mixed numbers in two and a half times three and two-fifths convert to the improper fractions five halves and seventeen-fifths.
- Step 3:
**Write the improper fractions**Write the improper fractions side-by-side on your paper. - Step 4:
**Multiply the numerators**Multiply the numerators and write the product as the numerator of your solution. - TIP: The product of five halves times seventeen-fifths will have a numerator of 85.
- Step 5:
**Multiply the denominators**Multiply the denominators and write the product as the denominator of your solution. - TIP: The product of five halves × seventeen-fifths will have a denominator of 10.
- Step 6:
**Simplify**Simplify the resulting fraction and write the solution as a mixed number. - FACT: The Rhind Mathematical Papyrus, from around 1650 B.C.E., contains 84 mathematical problems involving administrative and building works.
