Kevin needs to order 3,200 binder clips for an upcoming conference. If the binder clips come in boxes of 400, how many boxes should Kevin order?

To find the number of boxes Kevin should order, he needs to divide the total number of binder clips needed by the number of binder clips per box. In this case, 3,200 binder clips/ 400 binder clips per box = <<3200/400=8>>8 boxes. Therefore, Kevin should order 8 boxes. Answer: \boxed{8}.

To determine how many boxes Kevin should order, divide the total quantity of binder clips needed by the number of clips in each box.

Number of boxes = Total quantity needed / Clips in each box

Number of boxes = 3,200 / 400

Number of boxes = 8

Kevin should order 8 boxes of binder clips for the conference.
