Answer:
A) the graph represents 30 students in total because 9+10+6+5=30
B) 8 students prefer action or comedy over drama or sci-fi because if you add action and comedy together you get 19 and if you add drama and sci-fi together you get 11 and if you subtract 19-11 you would get 8
C) 1/3 of the students prefer comedies because the denominator (The bottom number) would be the total amount of students, which is 30, and the numerator (the top number) would be the students who like comedy, which is 10, so we put that into a fraction (10/30)- now both parts of the fractions are divisible by 10 so, 10 ÷ 10= 1 and 30 ÷ 10 = 3, so your final fraction would be 1/3
D) 3/10 of the students prefer action movies so we would do the same thing we did before for C, the total number of students in the denominator and the students who like action in the numerator to get 9/30, then 9 and 30 are divisible by 3 so 9÷3=3 and 30÷3=10 to get 3/10
