### Instruction:
 Leo has to write a 400-word story for his literature class. 10 words fit on each line of his notebook and 20 lines fit on each page. Lucas has filled one and a half pages. How many words does he have left to write?


### Response:
 Il a écrit 20 * 1.5 = <<20*1.5=30>>30 lignes.
Le nombre de mots écrits est de 30 * 10 = <<30*10=300>>300 mots.
Le nombre de mots restants est de 400 - 300 = <<400-300=100>>100 mots.
