Multiply & Divide fractions

**fraction lab:**

ow that you are confident with putting fractions in lowest terms and are working on your projects where you perform mixed to improper conversions, you are ready to learn how to MULTIPLY, & DIVIDE fractions.

**Watch the videos below IN ORDER!**This video gives you an overview of what multiplying fractions really means. Pay attention to the explanation of the word "of". You will notice that he does not put the answers in lowest terms (which we will be doing). Watch next video to learn about cross canceling.

You have the option of multiplying straight across then reducing the fraction (like the video above), or you can use cross cancelling first. By doing this first before multiplying straight across, your answer will be easier to simplify or may already be simplified. This video shows you how to cross cancel.

In this video you will learn how to multiply a whole number times a fraction. For example 20 x 3/4. Check out the different format. This one is taught by using a song and cartoon. Memorize the hook! 'Multiply by the top & divide the bottom!'

When multiplying mixed numbers times fractions or other mixed numbers, you HAVE to CONVERT them to IMPROPER FRACTIONS first. Watch this quick video that explain how to do this.

This video explains what dividing fractions means. You will also learn about a concept called 'reciprocal'.

Dividing fractions is very similar to multiplying fractions except one extra step first. Listen to this catchy song that will help you remember to 'Keep Change Flip'.

When dividing mixed numbers we MUST CONVERT them to IMPROPER FRACTIONS first! Then we use the Keep Change Flip to multiply by the reciprocal. Watch this video to see how this works.
