Answer:
66%
Step-by-step explanation:
The total number of seats in a theatre = 3200
The students filled 2112 of the seats in the theater.
We need to find the percentage of the seats in the theater were filled by the 6th graders on the trip. It is calculated as follows :
[tex]\%=\dfrac{2112}{3200}\times 100\\\\=66\%[/tex]
Hence, the required percentage is 66%.
