[{"id":50601,"question":"Quel est le résultat de 456 + 234 ?","option_a":"690","option_b":"680","option_c":"700","option_d":"670","option_e":"","option_f":"","bonne_reponse":"A","explication":"456 + 234 = 690. Additionnez les unités, puis les dizaines et enfin les centaines.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":50602,"question":"Un carré a un côté de 5 cm. Quel est son périmètre ?","option_a":"10 cm","option_b":"20 cm","option_c":"25 cm","option_d":"15 cm","option_e":"","option_f":"","bonne_reponse":"B","explication":"Le périmètre d'un carré se calcule par 4 × côté. Ici, 4 × 5 = 20 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":50603,"question":"Vrai ou Faux ? La division est une opération commutative.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"B","explication":"La division n'est pas commutative : 6 ÷ 2 ≠ 2 ÷ 6.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":50604,"question":"Quel est le résultat de 12 × 15 ?","option_a":"180","option_b":"170","option_c":"160","option_d":"190","option_e":"","option_f":"","bonne_reponse":"A","explication":"12 × 15 = 180. Utilisez la méthode de la distributivité : (10 × 15) + (2 × 15) = 150 + 30 = 180.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":50605,"question":"Vrai ou Faux ? Un triangle équilatéral a trois côtés égaux.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Par définition, un triangle équilatéral a ses trois côtés et ses trois angles égaux.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":50606,"question":"Quel est le résultat de 56 ÷ 8 ?","option_a":"6","option_b":"7","option_c":"8","option_d":"9","option_e":"","option_f":"","bonne_reponse":"B","explication":"56 ÷ 8 = 7. La division est l'inverse de la multiplication : 8 × 7 = 56.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":50607,"question":"Un rectangle a une longueur de 8 cm et une largeur de 3 cm. Quelle est son aire ?","option_a":"24 cm²","option_b":"22 cm²","option_c":"20 cm²","option_d":"26 cm²","option_e":"","option_f":"","bonne_reponse":"A","explication":"L'aire d'un rectangle se calcule par longueur × largeur. Ici, 8 × 3 = 24 cm².","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":50608,"question":"Vrai ou Faux ? 0 est un nombre premier.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"B","explication":"Un nombre premier a exactement deux diviseurs : 1 et lui-même. 0 n'est divisible que par lui-même.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":50609,"question":"Quel est le résultat de 3 × (4 + 5) ?","option_a":"27","option_b":"25","option_c":"30","option_d":"20","option_e":"","option_f":"","bonne_reponse":"A","explication":"Appliquez la priorité des parenthèses : 4 + 5 = 9, puis 3 × 9 = 27.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":50610,"question":"Vrai ou Faux ? Un cercle a une infinité de rayons.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Un cercle a une infinité de rayons car tous les points du cercle sont à la même distance du centre.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0}]
