Answer:
27 children
Explanation:
At this movie, the ratio of children to adults suggests that there are 27 children in attendance.
There are 9 children for every 4 adults.
This means that if there were 13 people, 9 of them would be children and 4 would be adults. Children would therefore be:
= 9 / 13
If there were 39 people, the number of children would be:
= 9/13 x 39
= 27 children
In conclusion, there are 27 children
