Rebeca Andrade of Brazil won gold, and Jordan Chiles of the U.S.
Towas awarded bronze after an inquiry.
Biles will take home three golds and a silver from Paris in what could be her last Games.
In a stirring — and vindicating — coda to her Olympics, Biles won her fourth medal of the Games, a silver to go along with her three golds, in the team competition, the all-around and the vault.
Rebeca Andrade of Brazil, who finished second to Biles in the all-around and vault, won gold with 14.166, edging out Biles (14.133) and
Jordan Chiles of the United States (13.766), who won bronze after a few moments of confusion.
