A missing fraction on a number line is located exacly halfway between 3/6 and 5/6. What is the missing fraction?

The missing number would be 4/6, or 2/3.

The missing number can be found by finding the absolute distance in between the numbers, dividing it and then adding it to the smaller number.

(5/6-3/6) / 2 = (2/6) / 2=1/6

3/6+1/6=4/6 or 2/3

I think it is 2/6 or 1/3
