Answer:

Kyle pretended to take a shower for #20%# of the times he was asked.

Explanation:

The times Kyle pretended to take a shower amount to #(330-264)#, that is #66#.

To determine what percentage #66# is of #330#, we write the equation:

#330xxx/100=66#

Multiply both sides by #100/330#.

#x=66xx100/330#

#x=66xx(10cancel(0))/(33cancel(0))#

#x=2cancel66xx10/cancel33#

#x=2xx10#

#x=20#
