[{"id":63062,"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":63063,"question":"Un rectangle a une longueur de 8 cm et une largeur de 5 cm. Son périmètre est de 26 cm.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Le périmètre se calcule par (Longueur + Largeur) × 2 = (8 + 5) × 2 = 26 cm. L'affirmation est donc vraie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":63064,"question":"Quel est le résultat de 145 ÷ 5 ?","option_a":"25","option_b":"29","option_c":"30","option_d":"35","option_e":"","option_f":"","bonne_reponse":"C","explication":"145 divisé par 5 donne 29. On peut vérifier en multipliant 29 × 5 = 145.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":63065,"question":"Un triangle équilatéral a tous ses angles égaux à 60 degrés.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Dans un triangle équilatéral, les trois angles sont égaux et leur somme fait 180°. Chaque angle mesure donc 60°.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":63066,"question":"Quelle est la fraction irréductible 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":"18\/24 se simplifie en divisant numérateur et dénominateur par 6, ce qui donne 3\/4.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":63067,"question":"Le nombre 0,75 est égal à 3\/4.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"0,75 = 75\/100 = 3\/4 après simplification. L'affirmation est donc vraie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":63068,"question":"Quel est le résultat de 12 × (8 - 3) ?","option_a":"45","option_b":"60","option_c":"75","option_d":"90","option_e":"","option_f":"","bonne_reponse":"B","explication":"On commence par calculer la parenthèse : 8 - 3 = 5. Puis on multiplie 12 × 5 = 60.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":63069,"question":"Un carré a une aire de 36 cm². Quelle est la longueur de son côté ?","option_a":"4 cm","option_b":"6 cm","option_c":"8 cm","option_d":"9 cm","option_e":"","option_f":"","bonne_reponse":"B","explication":"L'aire d'un carré est égale au carré de son côté. Donc côté = √36 = 6 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":63070,"question":"Le nombre 1,25 est supérieur à 1,2.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"1,25 \u003E 1,2 car 25 centièmes est supérieur à 20 centièmes. L'affirmation est donc vraie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":63071,"question":"Quelle est la somme des angles d'un quadrilatère ?","option_a":"180°","option_b":"270°","option_c":"360°","option_d":"540°","option_e":"","option_f":"","bonne_reponse":"C","explication":"La somme des angles d'un quadrilatère est toujours de 360°, quelle que soit sa forme.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0}]
