Of the 5,200 teens, 1040 said they do not enjoy going to the movies in their free time.

Explanation:

If we know #80%# of the #5,200# teens said they enjoy going to the movies, we know #20%# said they do not enjoy it.

To find #20%# of #5,200#, we convert #20%# to a decimal:
#20% = \frac 20 100 = 0.2#

And then we multiply this by #5,200#:
#0.2 \times 5,200 = 1040#

So, we know that #1040# teens said they do not enjoy going to the movies in their free time.
