5.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"C'est une règle de divisibilité classique : un nombre est divisible par 5 si son dernier chiffre est 0 ou 5.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\",

?","option_a":"4","option_b":"5","option_c":"6","option_d":"7","option_e":"","option_f":"","bonne_reponse":"c","explication":"6 est un diviseur de 18 car 18 ÷ 6 = 3, qui est un nombre entier.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"c\", \"options\": {\"a\": \"4\", \"b\": \"5\",

3.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"b","explication":"La règle de divisibilité par 9 exige que la somme des chiffres soit divisible par 9, pas seulement par 3.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\":
