Yes because 1/2 is right on the half and 2/7 is les than the half. You can also use the butterfly method. 1 times 7 is 7 and 2 times 2 is 4 1/2 is greater because 7 us greater than 4
for the y value you would go up the top line by 2 in problem 3 for the x value you would go to the left by 4 and follow the same steps but with different numbers for problem 4
