You can simplify it as... 3/6: Because that's 6/2 and 12/2, so the numerator and denominator recieve the same operations 2/4: Because it's 6/3 which = 2, and 12/4 which = 4 1/2: Because it's 6/6=1 and 12/6=2
I hope this helped! If you have any other questions, just ask, and I hope you have a great day! :)
