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

### Instruction:
 Lexi wants to run a total of three and one-fourth miles. One lap on a particular outdoor track measures a quarter of a mile around. How many complete laps must she run?


### Response:
 Il y a 3/1/4 = 12 un quart de mile dans 3 miles.
Donc, Lexi devra courir 12 (à partir de 3 miles) + 1 (à partir de 1/4 mile) = <<12+1=13>>13 tours complets.
