This problem belongs to which one doesn't belong

The question is:

Which number in the square above doesn`t belong to the square ? or in other words, which number in the square above is strange?

20 25 \frac{20}{25} 1 20 \frac{1}{20} 5 4 \frac{5}{4} 2 3 \frac{2}{3} All of them, or from other different point of view, none of them

1.- I can say 5 4 \frac{5}{4} doesn`t belong to the square because it is the only number bigger than 1, so this one is the strange one

2.- I can say 20 25 \frac{20}{25} doesn`t belong to the square because it is the only number not being simplified, so this one is the strange one.

3.- I can say 2 3 = 0. 6 ‾ \frac{2}{3} = 0.\overline{6} doesn`t belong to the square because it is the only periodic number, so this one is the strange one.

or

4.- I can say 1 20 \frac{1}{20} doesn`t belong to the square because it is the only unitary number (number with numerator 1) or because it's the only number which sum of distances to the other numbers is the greatest, so this one is the strange one.

So, all the numbers are strange or none of them is strange, or I can also say all the numbers belongs to the square or none of them perfectly fits...
