Question

There are 338 students and teachers going on a field trip to the zoo. Each bus holds 42 people. How many buses are needed for this trip?

Answer 1

First let's identify each part of the question. 338 is the total amount of people on the trip. 42 is how many people one bus holds. We need to find out "how many groups of 42 go into 338."

We can do this in two ways.

1. Count groups of 42 until we get as close to 338 as we can: 42+42+42 ... +42 = 336
2. This ends up being eight groups of 42. Because there are 2 people not accounted for (338 - 336 = 2), you would need an extra bus to sit the extra 2. So you need 9 buses (8+1 = 9) in total.
3. Divide 338 by 42 (using long division or a calculator): 338/42 = 8 r 2 or 8.04...
4. Because 42 does not go evenly into 338 (there is a remainder/ there is an extra decimal), you would have to round up to 9 buses (you can't have a "decimal" or "fractional" sized bus)

Answer 2

338/42 =8.04 so 9 busses

Answer 3

Divide and round the answer up since you can't send a partial bus!!!

Answer 4

First understand what the problem is asking you to solve. Here, the problem wants to know how many buses are needed.

Next, look to see what important has been given.

338 total students AND teachers or 338 people total. It also tells us that each bus holds 42 people.

"If bus has 42 people, how many buses are needed to hold 338?"

You can make groups of 42 and add them until you get to 338 (or above since it does not divide equally)

EXAMPLE: 42 + 42 + 42 + 42 + 42 + 42 + 42 + 42= 336.

There are still 2 people out of the 338 who need to get on a bus, so instead of 8 buses, you will need 9 even though it is not full.

Answer 5

338 / 42 = 8.047619048

9 busses are needed.
