[{"id":97569,"question":"Quel est le résultat de l'opération suivante : 15 × 4 + 12 ?","option_a":"72","option_b":"60","option_c":"52","option_d":"80","option_e":"","option_f":"","bonne_reponse":"a","explication":"15 × 4 = 60, puis 60 + 12 = 72. L'ordre des opérations (multiplication avant addition) est respecté.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"72\", \"b\": \"60\", \"c\": \"52\", \"d\": \"80\"}}","_debug_options_count":4},{"id":97570,"question":"Vrai ou Faux : La fraction 3\/4 est équivalente à 0,75.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"En divisant 3 par 4, on obtient bien 0,75. Les fractions et les nombres décimaux sont deux représentations d'une même valeur.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Vrai\", \"b\": \"Faux\", \"c\": \"\", \"d\": \"\"}}","_debug_options_count":4},{"id":97571,"question":"Quel est le périmètre d'un rectangle de longueur 8 cm et de largeur 5 cm ?","option_a":"26 cm","option_b":"40 cm","option_c":"13 cm","option_d":"30 cm","option_e":"","option_f":"","bonne_reponse":"a","explication":"Le périmètre d'un rectangle se calcule avec la formule P = 2 × (longueur + largeur). Ici, P = 2 × (8 + 5) = 26 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"26 cm\", \"b\": \"40 cm\", \"c\": \"13 cm\", \"d\": \"30 cm\"}}","_debug_options_count":4},{"id":97572,"question":"Vrai ou Faux : Diviser un nombre par 0 donne toujours 0.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"b","explication":"Diviser par 0 est une opération indéfinie en mathématiques. Elle n'a aucun sens et est donc impossible.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"Vrai\", \"b\": \"Faux\", \"c\": \"\", \"d\": \"\"}}","_debug_options_count":4},{"id":97573,"question":"Quelle est la somme des angles d'un triangle ?","option_a":"90°","option_b":"180°","option_c":"360°","option_d":"270°","option_e":"","option_f":"","bonne_reponse":"b","explication":"La somme des angles d'un triangle est toujours égale à 180°, quelle que soit sa forme.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"90°\", \"b\": \"180°\", \"c\": \"360°\", \"d\": \"270°\"}}","_debug_options_count":4},{"id":97574,"question":"Vrai ou Faux : 0,5 est supérieur à 0,75.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"b","explication":"0,5 est inférieur à 0,75. En comparant les décimales, on voit que 5 \u003C 7.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"Vrai\", \"b\": \"Faux\", \"c\": \"\", \"d\": \"\"}}","_debug_options_count":4},{"id":97575,"question":"Quel est le résultat de 45 ÷ 9 ?","option_a":"5","option_b":"4","option_c":"6","option_d":"7","option_e":"","option_f":"","bonne_reponse":"a","explication":"45 divisé par 9 donne 5, car 9 × 5 = 45.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"5\", \"b\": \"4\", \"c\": \"6\", \"d\": \"7\"}}","_debug_options_count":4},{"id":97576,"question":"Vrai ou Faux : Un nombre pair est toujours divisible par 2.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"Par définition, un nombre pair est un entier divisible par 2 sans reste.
