make all into a number
-3/8 = -0.375
52% = 52/100 = 0.52
13/20 = 0.65
then arrange in order of size
-2 , -0.42 , -0.375 , 0.52 , 0.65
therefore the order is
-2 , -0.42 , -3/8 , 52% , 13/20
 so -3/8, 52%, -.42, -2, 13/20

so -3/8=-0.375
52%=0.52
-0.42
-2
13/20=65/100=0.65
so order -0.375,0.52, -0.42, -2, 0.65
so the negative numbers are obviously smallest so
the farther away a negative number is from zero, the smaller it is
so the order of the negatives is -2, -0.42, -0.375 and the positives are 0.52, 0.65

so the order is -2, -0.42, -0.375, 0.52, 0.65
or -2, -.42, -3/8, 52%, 13/20
