Put them in the freezer and wait until frost forms on one of them. That will be the one closest to 0º C.

4/7 as a decimal is 0.'571428' recurring
500 thousandths = 500/1000= 500 x 1/500 x 2= 1/2= halfNot only is it closest to a half, it is a half.
zero aka 0
If 0, half or 1 refers to inches, the answer is 0.
5/8 is closest to a half.
There is no possible answer. For any given fraction, half that fraction is another fraction and it will be closer to 0. And then half of that will be closer still, and then half of that ... . Hope you get the idea.
Let's do the math: 1/5 = .20 0 = .00 1/2 = one half = .50 1/1 = one whole = 1.0 The distance between 1/5 and 0 is the shortest (only .20 away), and thus, 0 is the closest to 1/5.
2 fifths is equivalent to 0.4, which is closer to 0 than it is to 0.5 (1 half) or 1. To determine this, you can think of the number line where 0 is closer to 0.4 than 0.5, making 0 the closest whole number.
0 1.5-1.5=0

It's closer to zero than it is to one.

It is closer to one half.
