[{"id":3426,"question":"Quel est le résultat de l'opération suivante : 456 ÷ 3 ?","option_a":"152","option_b":"148","option_c":"150","option_d":"154","option_e":"","option_f":"","bonne_reponse":"a","explication":"Pour diviser 456 par 3, on effectue la division pas à pas : 3 × 150 = 450, reste 6, puis 3 × 2 = 6. Le résultat est donc 152.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"152\", \"b\": \"148\", \"c\": \"150\", \"d\": \"154\"}}","_debug_options_count":4},{"id":3427,"question":"Si un rectangle a une longueur de 8 cm et une largeur de 5 cm, quel est son périmètre ?","option_a":"26 cm","option_b":"30 cm","option_c":"40 cm","option_d":"13 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) = 2 × 13 = 26 cm. Attention à ne pas confondre avec l'aire (8 × 5 = 40 cm²).","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"26 cm\", \"b\": \"30 cm\", \"c\": \"40 cm\", \"d\": \"13 cm\"}}","_debug_options_count":4},{"id":3428,"question":"Quelle est la fraction simplifiée de 18\/24 ?","option_a":"3\/4","option_b":"9\/12","option_c":"6\/8","option_d":"2\/3","option_e":"","option_f":"","bonne_reponse":"a","explication":"Pour simplifier 18\/24, on divise le numérateur et le dénominateur par leur plus grand commun diviseur (PGCD), qui est 6. Ainsi, 18 ÷ 6 = 3 et 24 ÷ 6 = 4, d'où 3\/4.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"3\/4\", \"b\": \"9\/12\", \"c\": \"6\/8\", \"d\": \"2\/3\"}}","_debug_options_count":4},{"id":3429,"question":"Un triangle a deux angles de 50° et 60°. Quelle est la mesure du troisième angle ?","option_a":"70°","option_b":"80°","option_c":"90°","option_d":"100°","option_e":"","option_f":"","bonne_reponse":"a","explication":"La somme des angles d'un triangle est toujours égale à 180°. Ici, 50° + 60° = 110°, donc le troisième angle mesure 180° - 110° = 70°.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"70°\", \"b\": \"80°\", \"c\": \"90°\", \"d\": \"100°\"}}","_debug_options_count":4},{"id":3430,"question":"Quel est le résultat de 3\/5 + 2\/10 ?","option_a":"4\/10","option_b":"1\/2","option_c":"7\/10","option_d":"5\/15","option_e":"","option_f":"","bonne_reponse":"c","explication":"Pour additionner ces fractions, on les met au même dénominateur : 3\/5 = 6\/10. Ainsi, 6\/10 + 2\/10 = 8\/10, qui se simplifie en 4\/5 (ou 0,8).","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\/10\", \"b\": \"1\/2\", \"c\": \"7\/10\", \"d\": \"5\/15\"}}","_debug_options_count":4}]
