[{"id":112533,"question":"Quel est le résultat de 3,5 × 2 ?","option_a":"5,5","option_b":"6,5","option_c":"7","option_d":"7,5","option_e":"","option_f":"","bonne_reponse":"d","explication":"3,5 × 2 = 7. Multiplier un nombre décimal par 2 revient à doubler sa valeur.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"d\", \"options\": {\"a\": \"5,5\", \"b\": \"6,5\", \"c\": \"7\", \"d\": \"7,5\"}}","_debug_options_count":4},{"id":112534,"question":"Un rectangle a une longueur de 8 cm et une largeur de 5 cm. Quel est son périmètre ?","option_a":"13 cm","option_b":"26 cm","option_c":"30 cm","option_d":"40 cm","option_e":"","option_f":"","bonne_reponse":"b","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\": \"b\", \"options\": {\"a\": \"13 cm\", \"b\": \"26 cm\", \"c\": \"30 cm\", \"d\": \"40 cm\"}}","_debug_options_count":4},{"id":112535,"question":"Vrai ou Faux ? 0,75 est supérieur à 3\/4.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"b","explication":"0,75 = 3\/4. Les deux valeurs sont égales, donc l'affirmation est fausse.","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":112536,"question":"Quelle est la fraction irréductible de 12\/18 ?","option_a":"2\/3","option_b":"4\/6","option_c":"6\/9","option_d":"1\/2","option_e":"","option_f":"","bonne_reponse":"a","explication":"12\/18 se simplifie en divisant le numérateur et le dénominateur par 6 : 12 ÷ 6 = 2 et 18 ÷ 6 = 3, donc 2\/3.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"2\/3\", \"b\": \"4\/6\", \"c\": \"6\/9\", \"d\": \"1\/2\"}}","_debug_options_count":4},{"id":112537,"question":"Convertis 2,5 kg en grammes.","option_a":"25 g","option_b":"250 g","option_c":"2500 g","option_d":"25000 g","option_e":"","option_f":"","bonne_reponse":"c","explication":"1 kg = 1000 g, donc 2,5 kg = 2,5 × 1000 = 2500 g.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"c\", \"options\": {\"a\": \"25 g\", \"b\": \"250 g\", \"c\": \"2500 g\", \"d\": \"25000 g\"}}","_debug_options_count":4},{"id":112538,"question":"Vrai ou Faux ? La somme de deux angles complémentaires est toujours égale à 180°.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"b","explication":"Deux angles complémentaires ont une somme de 90°. La somme de 180° correspond à des angles supplémentaires.","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":112539,"question":"Quel est le résultat de 45 ÷ 5 ?","option_a":"8","option_b":"9","option_c":"10","option_d":"11","option_e":"","option_f":"","bonne_reponse":"b","explication":"45 divisé par 5 donne 9, car 5 × 9 = 45.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"8\", \"b\": \"9\", \"c\": \"10\", \"d\": \"11\"}}","_debug_options_count":4},{"id":112540,"question":"Un triangle isocèle a deux côtés de 6 cm et un côté de 4 cm. Quel est son périmètre ?","option_a":"10 cm","option_b":"16 cm","option_c":"18 cm","option_d":"20 cm","option_e":"","option_f":"","bonne_reponse":"b","explication":"Le périmètre se calcule en additionnant les longueurs des trois côtés : 6 + 6 + 4 = 16 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"10 cm\", \"b\": \"16 cm\", \"c\": \"18 cm\", \"d\": \"20 cm\"}}","_debug_options_count":4},{"id":112541,"question":"Vrai ou Faux ? 1\/2 + 1\/4 = 3\/4.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"Pour additionner des fractions, il faut un dénominateur commun. 1\/2 = 2\/4, donc 2\/4 + 1\/4 = 3\/4.
