11:19
5:7
Film B

Answer 1

To compare the proportion of children in the audience for both films, we can calculate the percentage of children in each audience.

For Film A, the ratio of children to adults is 11:19, which means that the total number of parts is 11 + 19 = 30.

The percentage of children in Film A audience is:

(11/30) x 100% = 36.67%

For Film B, the ratio of children to adults is 5:7, which means that the total number of parts is 5 + 7 = 12.

The percentage of children in Film B audience is:

(5/12) x 100% = 41.67%

Since the percentage of children in Film B audience is greater than that of Film A, we can conclude that Film B has a greater proportion of children in the audience. Therefore, the answer is Film B.
