Well, there might be some better ones out there, but this is a compiled 1-page-tried-to-make-simplified print out for students that need a quick reference guide for adding, subtracting, multiplying and dividing fractions. It's a little more extensive than just the basics, I tried to include examples too. I haven't printed it yet, so I hope it prints with clarity. anyway, students can fold it in half and keep as a reference. please limit 30 print-outs per purchase. ENJOY!
