The answer is 1/2 because of how many times does 2 go into 2 which is 1 and how many times 2 can go into 4 which is 2. So 1 would go on top and the 2 would go on the bottom
find a number that goes into both numbers. however many times that number goes into one of the numbers on the fraction, it gets to replace that number. I just confused myself, but I hope you understand. the actuall answer is 1/2.
