Joe · Answer 1

Here, we need to set up a proportion.

3/2100 = x/2800

Cross multiply.

3*2800 = 8400

2100*x = 2100x

2100x = 8400

2100x/2100 = 8400/2100

x = 8400/2100

x = 4

Final answer: It will take 4 hours to fill 2800 seats

Saniyah Madden · Answer 2

It would take 4 hours to fill a concert hall that has 2,800 seats because it takes 3 hours for 2,100 people to fill and 2,100/3=700 so 700*4=2,800.
