Question

There was a total of 640 students at a school on Friday. Every student either walked or rode in a bus to the school. If 45% of the total number of students walked to the school on Friday, how many of the students rode in a bus to the school

Answer 1

The question involves calculating the number of students who took the bus by subtracting the percentage of students who walked (45%) from 100% to find that 55% took the bus. Multiplying the total number of students (640) by 55% yields 352 students who rode the bus.

Step-by-step explanation:

The question requires calculating the number of students who rode a bus to school based on the percentage who walked.

Given that 45% of the students walked to school, we can infer that the remaining percentage took the bus.

Since percentages sum up to 100%, we can subtract 45% from 100% to find the percentage of students who took the bus.

This calculation gives us 55% of the students.

To find out how many students this percentage represents, we multiply the total number of students, which is 640, by 55% (or 0.55 in decimal form).

Therefore, the number of students who rode a bus to school is:
640 students * 0.55 = 352 students.
