We first order them on the whole number part.

Explanation:

Then we get the fraction part in order on basis of common denominators
(A) #1 7/8 and 1 75/100=1 3/4=1 6/8#

(B) #2 1/4 and 2 4/10=2 2/5#
Common denominators:
#2+1/4xx5/5=2 5/20 and 2+4/10xx2/2=2 8/20#

Now we can order them:
(1) #1 6/8 = 1.75#
(2) #1 7/8#
(3) #2 5/20=2 1/4#
(4) #2 8/20=2.4#
