After some reflection Mayor 1 agreed to go though feeling out of place not thinking of itself as a “real” fraction and wondering how it would be received by 4/6's friends. Also, mayor 1's part in the movie was small. But that didn't matter. 4/6 wanted it's co-star to be at the party.
After a short walk following a lovely path, they get to the party and there are several of 4/6's friends greeting them and praising both of them for their great performances in The Weird Number. The mayor was pleasantly surprised at being welcomed, despite being a natural number.
“You’re one of us,” said 4/6.
“But, what fraction am I?” asked the mayor.
