Lizzy: A conference center has six rooms. Each room can hold up to 80 people. Today, the conference center is only 2/3 full. How many people are in the conference center?.
Me: Hmmm, let me think. I think this is the detailed solution:
The conference center can hold up to 80 x 6 = 480 people. Today, there are 480 x 2 / 3 = 320 people in the conference center. Final answer: 320.
