Question

The fifth-grade classes at Brookfield School used five identical buses to go on a field trip. •There were a total of 40 seats on each bus. •All of the seats on four buses were filled. •The fifth bus had 4/5 of the seats filled. •1/8 of all the passengers on the buses were adults. How many adults went on the field trip.

Answer 1

First things first, you need to figure out the amount of passengers on the fifth bus.

Solution:
40 x 4
--      -  = 32 passengers
 1  x 5
*The fifth bus has 32 people.
You can now figure out the total number of passengers in all of the buses.

(40 x 4) + 32 = 192
*Overall, all 5 buses have a total of 192 passengers.
Since you have the total number of passengers, you can now figure out the numbers of adults who went on the field trip, which is 1/8 of all the passengers.

Solution:
192 x 1
-----    - = 24 passengers
  1   x 8

The final answer is: 24 adults went on the field trip.

Answer 2

The number of adults who went on the field trip is mathematically given as

5+5+5+5+4 = 24

What is the number of adults who went on the field trip?

Question Parameter(s):

There were a total of 40 seats on each bus

The fifth bus had 4/5 of the seats filled

1/8 of all the passengers on the buses were adults

four full buses

= 40/8

= 5

4/5 filled bus

40/4/5

= 32

32/8

= 4

In conclusion, the number of adults who went on the field trip is

5+5+5+5+4 = 24
