Final answer:
When dividing 345 students by the capacity of 47 students per bus, 7 buses will be completely filled.
Step-by-step explanation:
The student has asked how many buses will be completely filled when 345 students are signed up for a field trip, and each bus can hold 47 students. To solve this, we need to divide the total number of students by the number of students each bus can hold. The calculation is as follows:
- Divide 345 (the total number of students) by 47 (the bus capacity).
- 345 ÷ 47 = 7 with a remainder, meaning 7 buses will be completely filled.
The remainder of students will need to be accommodated on an additional bus, but the question specifically asks for completely filled buses, so we do not count the additional bus that's only partially filled. Therefore, 7 buses will be completely filled.
