Answer: Because of the total number of DVDs given (36)the number of individual type of DVD are coming in decimals such that
Number of comedy films =11.07
Number of Action films =22.15
and Number of horror films =2.78
I also solved using total number of DVDs as 26 and the results were as follows
Number of comedy films =8
Number of acton films =16
and Number of horror films =2
Explanation:
Total number of DVD collection = 36
ratio of the type of DVD =comedy films to action to horror = 4:8: 1
Total ratio =4+8+1 = 13
Number of comedy films = ratio of comedy films/ total ratio x Total DVD collection
= 4/13 x 36= 11,.07 rounded to 11 comedy films
Number of action films = ratio of action films/ total ratio x Total DVD collection
= 8/13 x 36= 22.15 rounded to 22 action films
Number of horror films = ratio of horror films/ total ratio x Total DVD collection
1/13 x 36=2.78 rounded t0 3 Horror movies .
The numbers of each DVD are giving decimal numbers .
Using
Total number of DVD collection as 26.
we have that
Number of comedy films= 4/13 x 26 = 8
Number of action films= 8/13 x 26= 16
Number of Horror films = 1/13 x 26 = 2
