[{"id":72742,"question":"Quel est le résultat de 35 + 27 ?","option_a":"52","option_b":"62","option_c":"72","option_d":"82","option_e":"","option_f":"","bonne_reponse":"B","explication":"35 + 27 = 62. Additionnez les unités (5+7=12) puis les dizaines (30+20=50), puis additionnez les résultats (50+12=62).","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":72743,"question":"Un rectangle a une longueur de 8 cm et une largeur de 5 cm. Quel est son périmètre ?","option_a":"26 cm","option_b":"36 cm","option_c":"40 cm","option_d":"13 cm","option_e":"","option_f":"","bonne_reponse":"A","explication":"Le périmètre d'un rectangle se calcule par la formule P = 2 × (longueur + largeur). Ici, P = 2 × (8 + 5) = 2 × 13 = 26 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":72744,"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 est égal à 3\/4 (car 3 ÷ 4 = 0,75). Ils sont donc égaux, pas supérieurs.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":72745,"question":"Quel est le résultat de 12 × 0,5 ?","option_a":"6","option_b":"12","option_c":"24","option_d":"0,6","option_e":"","option_f":"","bonne_reponse":"A","explication":"Multiplier par 0,5 revient à diviser par 2. 12 ÷ 2 = 6.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":72746,"question":"Un carré a un côté de 6 cm. Quelle est son aire ?","option_a":"12 cm²","option_b":"24 cm²","option_c":"36 cm²","option_d":"6 cm²","option_e":"","option_f":"","bonne_reponse":"C","explication":"L'aire d'un carré se calcule par la formule A = côté × côté. Ici, A = 6 × 6 = 36 cm².","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":72747,"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. L'affirmation est donc vraie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":72748,"question":"Quel est le résultat de 45 ÷ 9 ?","option_a":"4","option_b":"5","option_c":"6","option_d":"7","option_e":"","option_f":"","bonne_reponse":"B","explication":"45 ÷ 9 = 5, car 9 × 5 = 45.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":72749,"question":"Un triangle équilatéral a un côté de 5 cm. Quel est son périmètre ?","option_a":"10 cm","option_b":"15 cm","option_c":"20 cm","option_d":"5 cm","option_e":"","option_f":"","bonne_reponse":"B","explication":"Un triangle équilatéral a trois côtés égaux. Le périmètre est donc 3 × 5 = 15 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":72750,"question":"Vrai ou Faux : 0,25 est égal à 1\/4.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"0,25 est égal à 1\/4 (car 1 ÷ 4 = 0,25). L'affirmation est donc vraie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":72751,"question":"Quel est le résultat de 7 × 8 ?","option_a":"48","option_b":"56","option_c":"64","option_d":"72","option_e":"","option_f":"","bonne_reponse":"B","explication":"7 × 8 = 56. C'est une multiplication de base à connaître par cœur.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0}]
