#75%# of #60# equals #45#.

Explanation:

We know that taking #75%# of something is the same as multiplying it by #0.75#. This means we can put up the following equation:
#x*0.75=45#

Now we can divide both sides by #0.75# to isolate #x#:
#(x*cancel0.75)/cancel0.75=45/0.75#

#x=45/0.75=(45*4)/(0.75*4)=180/3=60#
