Video Summary

Amy set aside the one kilogram weight. The total weight of all six weights is 21 kilograms. To balance the scales, the total weight on the scales must be an even number. By removing an odd weight, the remaining total becomes even. Since Amy used the five-kilogram weight, putting aside the one-kilogram weight allows for the remaining five weights to balance at 20 kilograms (10 kilograms per side). If she had put aside the three-kilogram weight, it wouldn't balance properly since it would require the use of the three-kilogram weight. Thus, the one-kilogram weight is set aside.
