Kelly and Chris packed several boxes with books. If Chris packed 60 percent of the total number of boxes, what was the ratio of the number of boxes Kelly packed to the number of boxes Chris packed?
Let, the TOTAL number of boxes = 10
So, Chris packed 6 boxes, and Kelly packed the remaining 4 boxes.
Ratio of the number of boxes Kelly packed to the number of boxes Chris packed = 4 : 6 = 2 : 3
