A long time ago some ancients needed to make 5 weights that could weigh any amount of weight up to 121 grams.

The ancients though, had only a 1 gram weight and 120 grams of clay(which they would later make into weights. So with only a scale, 120 grams of clay and a 1 gram weight how would you create all the other weights needed to weigh any amount up to 121 grams?

What is the minimum amount of weighings required to do this?

(In reply to re: Posted Solution Not Minimum by Irina)

This solution divides the weights, but it does not make them able to be added to make all possible intiger masses between 1 and 121.
