Step-by-step explanation:
Differentiate xy using the product rule, then
Given
x - y = xy
1 - = x.
+ y. 1 = x
+ y ( subtract 1 from both sides )
- = x
+ y - 1 ( subtract x
from both sides )
- - x
= y - 1 ( multiply through by - 1 )
+ x
= 1 - y
(1 + x) = 1 - y ← divide both sides by (1 + x)
=

Which is ordered in ascending order
To do this, it is best to convert the fractions to decimal and then make comparison.
From the options, only (b) is ordered in ascending order and the proof is as follows.
Convert to decimals
By comparison:
Hence, (b) is ordered from least to greatest
