Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 Bill has played 200 games of poker and won 63% of them. If he plays 100 more games and loses 43 of them, what is his new win percentage?


### Response:
 Bill a remporté 200 * 63% = <<200*63*.01=126>>126 parties sur 200.
Bill a un total de 200 + 100 = <<200+100=300>>300 parties jouées après avoir joué 100 parties supplémentaires.
Le total des victoires de Bill sera de 126 + 100 - 43 = <<126+100-43=183>>183 parties après avoir joué 100 parties supplémentaires.
Le nouveau pourcentage de victoires de Bill sera de 183 / 300 = 61%.
