Numbertown ---- Group Fractions: A Review
 All fractions are masters of disguise. For example, 4/6, 6/8 and 8/12 are all costumes in 2/3's closet and 2/3 can wear anyone of them at any time. What makes that possible? Their shaded ID parts are exactly the same which means they are equivalent. Every group of equivalent fractions is named after its “simplest” (in lowest terms) fraction. In this case, that fraction is 2/3. So 2/3 heads up the 2/3 group of costumes! Every unique fraction in Fractionville can take on many equivalent forms. In fact, there are so many that you can’t count them all! Another way to think about equivalent fractions is as “clones” of each other.  You can clone any fraction by multiplying or dividing BOTH the numerator (top number) and the denominator (bottom number) by the same number. For example, 2/3 and 4/6 are clones. Why? Because if you multiply the top and bottom numbers of 2/3 by 2 you get 4/6. And we know from watching the movie that 4/6 is the same as the fugitive 2/3.    For example, to clone 3/5 so it becomes 12/20, what should you multiply the numerator and denominator by? You got it, the number is 4. Do you see how that works? You can also use division to “clone down” which reduces the fraction. If you divide both numerator and denominator of 4/6 by 2 you get an equivalent fraction, 2/3. Amazing.
