To divide fractions, you have to keep the first fraction, change the division sign to a multiplication sign, and use the last fraction's reciprocal (flip) (SEE VOCAB POST), cross factor if possible (SEE POST ABOVE) then do the easy, multiplication problem. Be sure to simplify the product.
EASY TRICK: KCF (keep, change, flip). see above...
Ex.: 5/7 divided by 2/6
is the same as:
5/7 x 6/2= 30/14 = 2 2/14 = 2 1/7 (to learn to change improper fraction to a mixed number or vise versa see a post above)
