there would be 352 students carrying a backpack to school.
Question: d, both 5 goes into 20 and 440.On the first day of school, 20 out of the first 25 students who entered the school were carrying a backpack. Based on this information, if 440 students were at school, how many students could be expected to be carrying a backpack?
Answer: 352
Explanation: on the top of my head, both 20 and 440 go into 5. 5 * 4 is 20, 88 * 5 is 440. use the 88 and 4 and multiply, the 5's u will not use because the are a common number in both equations. 88 * 4 is 352.
Hope this helps!!!!!!!!!!!!!!!
