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
2/7 = 8/28
7/28 + 8/28 = 15/28
14/28 = 1/2 and 15/28 is close to 14/28
