Identify Students and Percentage: Identify the total number of students and the percentage that walked to school. The total number of students is 640, and 45% of them walked to school.Calculate Students Who Walked: Calculate the number of students who walked to school. To find out how many students walked, multiply the total number of students by the percentage that walked, expressed as a decimal. Number of students who walked = 45% of 640 = 0.45 × 640Find Number of Students Who Walked: Perform the calculation to find the number of students who walked. 0.45 × 640 = 288 So, 288 students walked to school.Calculate Students Who Rode Bus: Subtract the number of students who walked from the total number of students to find the number of students who rode in a bus. Number of students who rode in a bus = Total number of students - Number of students who walked Number of students who rode in a bus = 640 - 288Find Number of Students Who Rode Bus: Perform the subtraction to find the number of students who rode in a bus. 640 - 288 = 352 So, 352 students rode in a bus to school.
