how do i awnser this

Answer:
Step-by-step explanation
Firstly we are told that the ratio of the Circle and the Stalls is 2:5
Now we are also told that on Friday all the 528 seats in the Circle were taken and only 2/3 of the Stalls were taken.
If we know that there are 528 seats in the Circle, we could work out the maximum amount of seats in the Stalls.
C : S
2 : 5
528 : ?
So we can now use this to find the multiplier from 2 and 528.
528÷2=264
Which now means we can multiply 5 and 264 to find the maximum amount of seats in the Stalls.
5×264=1320
C : S
2 : 5
528 : 1320
We are also told that on Friday 2/3 of the seats were taken in the Stalls. To find 2/3 of 1320 we divide 1320 by the denominator...
1320÷3=440
...and times by the top...
440×2=880
The final part of the question states that we have to find the percentage of all the seats filled. To find the maximum amount of seats on both levels, we have to add 528 and 1320
528+1320=1848 seats in total that COULD be filled
528+880=1408 seats that were filled on Friday
This is shown in the fraction as 1408/1848
We then divide these...
1408÷1848= 0.7619...
Times that by 100...
0.7619...×100=76.1904....
Rounded to two significant figures gives...
