To find the answer, add all the numbers up in the pie graph.
=800
Now out of that 800, how many movies are Drama? 200/800, otherwise 1/4.
Now with a total of 3200 movies, 1/4 of 3200 is the answer. To find the answer, multiply the decimal form of the fraction by 3200.
.25*3200=800
So, if the survey was extended to include 3200 people, 800 people would prefer Drama.
