You do 3 over 4 times 8 which equals 6. Then you take 1 over 3 times 9 which equals 3. Then you take 6-3 and it equals 3. So your answer would be 3
If you want to calculate 18/4.52, you can do this using the following steps:
18/4.52 = 18 / 4 52/100 = 18 / 452/100 = 18 * 100/452 = 1800/452 = 450/113 = 3.98

The answer to your problem is going to be that there is a total of 432 seats in each movie area. you get this by multiplying 18 and 24 together. this is because there is 24 seats in each of the 18 rows. it is the same as finding the area of a rectangle, length * width.
1.41 in short. Hope this helps :)
