In an auditorium, 1/3of the 900 seats are empty and 2/3of the total seats (900)are filled after 1 hour. Then, the auditorium is
To find out the number of seats filled after 1 hour, we need to calculate 2/3 of the total seats (900).
2/3 * 900 = 600 seats
We know that 600 seats are filled after 1 hour. Now, to find the number of empty seats, we need to subtract the filled seats from the total seats.
Total seats - Filled seats = Empty seats
900 - 600 = 300 seats
Therefore, after 1 hour, there are 300 empty seats in the auditorium.
To determine the total number of seats in the auditorium, we'll first need to find the number of seats that are filled.
From the information given, we know that after 1 hour, 2/3 of the total seats (900) are filled. This means that 2/3 of 900 seats are filled.
To find the number of seats filled, we'll multiply the total number of seats by 2/3:
(900) x (2/3) = 1800/3 = 600 seats filled.
Since 2/3 of the total seats are filled, the remaining 1/3 of the seats must be empty. We can find the number of empty seats by multiplying the total number of seats by 1/3:
(900) x (1/3) = 900/3 = 300 empty seats.
Now, to find the total number of seats in the auditorium, we'll add the number of filled seats to the number of empty seats:
600 filled seats + 300 empty seats = 900 total seats.
Therefore, the auditorium has a total of 900 seats.
You may either want the fraction full, the fraction empty, the number of seats full, or the number of seats empty... you have not actually asked a question.
But...
If we figure out how many seats are EMPTY at the end of the hour you can figure the rest out.
At the start 1/3(900) are empty... so 300 empty, and 600 at the beginning are full.
After 1 hour 2/3 of the seats are now full (of the 300 still empty)
so...
2/3(300) = 200
So at the end of 1 hour there are 200 of the 900 still empty : )
