Answer :


First we must convert all the values to one mathematical state. We shall convert each to its decimal figure.

a) 0.5 is already a decimal so we leave it alone

b) 1: 5 when simplified makes 1/6 = 0.16

c) 0.35 is already a decimal so we will not touch it.

d) 12/25 = 0.48

e) 4/5 = 0.8

so now we arrange these from the least to greatest:

b, c, a, d, e,

now we equate this with the original values so the answer will be:

1:5, 0.35, 0.5, 12/25, 4/5
