Multiplying is easy!

I learned in class this week that there are three simple steps in multiplying fractions. The three simple steps are to first muliply the top numbers which are the numerators, then multiply the bottom numbers which are the denominators, last simplify the fraction if needed. You can look at my examples above. The easy thing about multiplying fractions is you do not have to worry about getting the denominators to be the same number. The link that you see here http://www.youtube.com/watch?v=19s-HKWQmMw will help you better understand fraction multiplication.
When you simplify fractions, you need to ask yourself what can I divide by using both numerator and denominator to get "nice" numbers. Let's say you would like to simplify this: 16/24. First you need to ask yourself what is the number I can divide both numbers by? That number is 4! So now you have, 4/6. Can you simplify this? Yes you can! Let's divide by 2. So now you have 2/3.  Great job! There is much more to multiplying fractions, I gave you the basic steps.
