[{"id":65202,"question":"Quel est le résultat de 245 + 137 ?","option_a":"372","option_b":"382","option_c":"392","option_d":"402","option_e":"","option_f":"","bonne_reponse":"B","explication":"245 + 137 = 382. Additionnez d'abord les unités (5+7=12), puis les dizaines (40+30=70) et enfin les centaines (200+100=300).","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":65203,"question":"La multiplication est une opération commutative.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Vrai. La multiplication est commutative : a × b = b × a. Par exemple, 3 × 4 = 4 × 3.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":65204,"question":"Quel est le périmètre d'un carré de côté 5 cm ?","option_a":"10 cm","option_b":"15 cm","option_c":"20 cm","option_d":"25 cm","option_e":"","option_f":"","bonne_reponse":"C","explication":"Le périmètre d'un carré se calcule par 4 × côté. Ici, 4 × 5 cm = 20 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":65205,"question":"Convertissez 3,5 kg en grammes.","option_a":"35 g","option_b":"350 g","option_c":"3 500 g","option_d":"35 000 g","option_e":"","option_f":"","bonne_reponse":"C","explication":"1 kg = 1 000 g. Donc, 3,5 kg = 3,5 × 1 000 g = 3 500 g.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":65206,"question":"Un angle droit mesure 90 degrés.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Vrai. Par définition, un angle droit mesure exactement 90 degrés.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":65207,"question":"Quel est le résultat de 128 ÷ 8 ?","option_a":"14","option_b":"16","option_c":"18","option_d":"20","option_e":"","option_f":"","bonne_reponse":"B","explication":"128 ÷ 8 = 16. Vérifiez en multipliant : 16 × 8 = 128.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":65208,"question":"Un triangle isocèle a deux côtés de même longueur.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Vrai. Un triangle isocèle possède deux côtés égaux et deux angles égaux.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":65209,"question":"Calculez 0,75 + 1,25.","option_a":"1,50","option_b":"1,75","option_c":"2,00","option_d":"2,25","option_e":"","option_f":"","bonne_reponse":"C","explication":"0,75 + 1,25 = 2,00. Additionnez les parties décimales puis les unités.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":65210,"question":"La division est l'opération inverse de la multiplication.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Vrai. Si a × b = c, alors c ÷ b = a et c ÷ a = b.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":65211,"question":"Quel est le résultat de 5 × (3 + 2) ?","option_a":"15","option_b":"20","option_c":"25","option_d":"30","option_e":"","option_f":"","bonne_reponse":"B","explication":"Calculez d'abord la parenthèse : 3 + 2 = 5. Puis multipliez : 5 × 5 = 20.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0}]
