These are fractions, so when 22nddoing fractions, we would first see which of the bottom denominator is bigger and see if the numerator is close to it or not.
(First): 2/6. This would be less than half.
(Second): 1/2. This would be early at half.
(Third): 6/8 This would be over half.
All of these would be all in order from least to greatest.
