See a solution process below:

First, rewrite the expression as:

#1/2 - 2#

We can now put the term on the right over a common denominator by multiplying by the appropriate form of #1#:

#1/2 - (2/2 xx 2) =>#

#1/2 - 4/2#

We can now subtract the numerators over the common denominator:

#(1 - 4)/2 =>#

#-3/2#
