    The best estimate for this sum is 1/2

    This is because because if we make the expression into a decimal it would be 0.53571428.. and many other numbers. If you make 1/4 into a decimal it will be 0.25 which is not close to the other number. Where-as if we made 1/2 into a decimal it would be 0.5 which would be the closest. Hope this helps

    Answer:
    The sum is close to 1/2
    Step-by-step explanation:
    1/4 = 7/28
    2/7 = 8/28
    7/28 + 8/28 = 15/28

    14/28 = 1/2 and 15/28 is close to 14/28
