A waiting room is 2/3 full when 36 people are seated. How many people are in the waiting room when it is 1/2 full?
1 answer:
When 36 people are seated the room is 2/3 full.
So for 1/3 , 18 people are needed
It will be 3/3 full if 54 people are present
So there can be 54 people in total
Now for the room to be 1/2 full , people will be 1/2 x 54 = 27 people
