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

### Instruction:
 Philip has a farm with animals. He has 20 cows, 50% more ducks. Philip also has as many pigs as one-fifth of ducks and cows in total. How many animals does Philip have on his farm?


### Response:
 Philip a 50/100 * 20 = <<50/100*20=10>>10 canards de plus que les vaches.
Cela signifie qu'il a 20 + 10 = <<20+10=30>>30 canards.
Philip a 20 + 30 = <<20+30=50>>50 vaches et canards au total, donc il a 1/5 * 50 = <<1/5*50=10>>10 cochons.
Donc au total, Philip a 20 + 30 + 10 = <<20+30+10=60>>60 animaux sur sa ferme.
