Akey component to this story is that the jeweler deceptively replaced “an equal weight” (or equal mass) of gold with silver. how does this action result in increasing the volume of the crown? explain using one or more equations.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
