The answer is -0.5, -1/3, 1/3, 0.5, 1.25.
This is because, if you convert all the fractions into decimals, it will be -0.5, -0.33333, 0.333333, 0.5, and 1.25. For positive numbers you order it from least to greatest. For negative integers, I ignore the sign and order it, but in reversed order as the question asks. If this method is too hard, then just think that for negative integers, it is just like an opposite world where big things are smaller.
