First, let's see all that's bigger than 1:
1.1, 5/3,(that's about 1.6) 2.0,
and we order them:
1.1, 5/3, 2.0,
then, bigger than 0, smaller than 1:
1/2(=0.5), ,0.4,5/8 (that's about 1.6):
ordering:
0.4, 1/2,5/8
And we're left with the one negative number, -2, that's the smallest.
Putting everything together:
-2, 0.4, 1/2,5/8 ,1.1, 5/3, 2.0,
