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

### Instruction:
 Ali has $480. He spent half of it on food, and then he spent a third of what was left on a pair of glasses. How much money did he have left?


### Response:
 Half of $480 is $480/2 = $<<480/2=240>>240.
Ali has $480 - $240 = $<<480-240=240>>240 left.
A third of $240 is $240/3 = $<<240/3=80>>80.
He spent $80, so he has $240 - $80 = $<<240-80=160>>160 left.
