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

### Instruction:
 John spent 3 years of his life exploring the jungle.  He then spent half as much time writing up notes about his travels.  It took .5 years to write his book once he was done with the notes.  How long did he spend on his book and exploring?


### Response:
 Il a passé 3 * 0,5 = <<3*.5=1.5>>1,5 ans à compiler des notes.
Il lui a fallu encore 0,5 = <<.5=.5>>0,5 ans pour écrire le livre.
Donc, au total, il lui a fallu 1,5 + 0,5 = <<1.5+.5=2>>2 ans pour tout écrire.
Il a donc passé 3 + 2 = <<3+2=5>>5 ans sur son livre et à explorer.
