# Multiplying Mixed Numbers Worksheets

You will find the skill that we investigate here particularly helpful when you are working with recipes. When you are at department retail store sales you are going to wish you knew this skill well to. We previously explored the concept of values that are composed of a whole number and a fraction that are called mixed numbers. We now work on using the multiplication operation with these values. This requires that you think back to using the same operation with fractions. When we multiply fractions, we find the product of numerators and place them over the product of the denominators. We perform that same operation, but we first convert mixed number values to improper fractions. These worksheets and lessons will help you explore this operation and learn to master it quickly.

### How to Find the Product of Mixed Numbers

Finding the products of proper and improper fractions is easy. All you have to do is multiply all the numerators together and multiply all the denominators together. The resulting fraction is the answer. There is a third type of fraction that kids must understand that is known as a mixed number. These values consist of a whole number and a fraction. A mixed number looks like this: 1 ¼ .

When we need to multiply two mixed numbers together there is a simple strategy that you can do to get this right every time. Work through an example by finding the product of 1 ¾ and 2 ⅗ .Here are the steps that we need to take, in order:

Step 1: Convert Mixed Numbers into Improper Fractions - The first step to multiply mixed numbers is to convert all values into improper fractions. We do this by multiplying the whole number with the denominator. We take that value and add it to the numerator. The value of the improper fraction is that product over the starting denominator. Let's put into work on this problem:

a) Converting 1 ¾ to an improper fraction = whole number (1) times denominator (4) = 4. We take that value (4) and add it to our current numerator (3) = 7. Our improper fraction is therefore: 7/4.

b) Converting 2 ⅗ to an improper fraction = whole number (2) times denominator (5) = 10. We take that value (10) and add it to our current numerator (3) = 13. Our improper fraction is therefore: 13/5.

Step 2: Multiply - The next step is to multiply the numerators together (tops) and the denominators together (bottoms). It should appear like this (numerator 1 x numerator 2) / (denominator 1 x denominator 2).

Problem: 7/4 x 13/5. When we fit it into the proper format it comes out as: (7 x 13) / (4 x 5) = 91/20.

Step 3: Simplify - Simplify the resulting fraction where possible! We can convert this back to a mixed number. The denominator goes into the numerator 4 times with a remainder of 11. This means that 91/20 = 4 11/20.
