Fractions...Divide to get Bigger?!

Welcome to a review of Day 2 with fractions!  This time we experienced dividing a fraction by a fraction.  We took the information we gained from yesterday's class and now we have added in the dividing aspects and left everything else the same!  When you divide a fraction by a fraction they simply need to remember to "flip the second one and multiply!"  Nothing too crazy, because everything else remains the same as yesterday after that!  I have provided two examples for you as a visual reminder in case your child is struggling and might need some extra help.  The first is multiplying straight across and the second is using the cross-cancel method.  If you click on the picture it will appear in a separate screen.

At the end of the problem what should we always check...............that the fraction is REDUCED fully!

When we divide fractions the answer will sometimes get bigger!  Just like the second example...why?  Because when you have a set amount of something and then divide that amount into several pieces that are a smaller than the original, you now have more pieces than you started with!
