Your answer:  If I want to minimize trips to teh scale, I'd say 7. 
Explanation:  OK, the scale only weighs 1Kg at a time, but wheat has a uniform density, so I ask my workers to make nine fairly equal piles of wheat. Then I take one pile of wheat and weigh it in 1kg increments.
Nine is a good number because it is the largest number you can remember without writing it down. Each pile should weigh whatever it weighs (actually 7kg), and with a weight of 1kg, it's seven trips to the scale. Of course you have the work of shoveling all those piles.
