[{"id":21368,"question":"Quel est le résultat de l'opération 3\/4 + 1\/2 ?","option_a":"5\/6","option_b":"7\/8","option_c":"1","option_d":"5\/4","option_e":"","option_f":"","bonne_reponse":"B","explication":"Pour additionner deux fractions, il faut les mettre au même dénominateur. 3\/4 + 2\/4 = 5\/4.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":21369,"question":"Un carré a un périmètre de 20 cm. Quelle est la longueur de son côté ?","option_a":"4 cm","option_b":"5 cm","option_c":"10 cm","option_d":"20 cm","option_e":"","option_f":"","bonne_reponse":"B","explication":"Le périmètre d'un carré est égal à 4 fois la longueur de son côté. Donc 20 cm \/ 4 = 5 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":21370,"question":"Vrai ou Faux : 0,75 est égal à 75%.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"0,75 est bien égal à 75%, car 0,75 × 100 = 75%. L'affirmation est donc vraie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":21371,"question":"Quel est le résultat de 7 × (3 + 2) ?","option_a":"25","option_b":"35","option_c":"40","option_d":"50","option_e":"","option_f":"","bonne_reponse":"B","explication":"D'abord, on calcule la parenthèse : 3 + 2 = 5. Ensuite, 7 × 5 = 35.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":21372,"question":"Vrai ou Faux : Un triangle équilatéral a trois angles de 60°.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Un triangle équilatéral a trois angles égaux à 60°, car la somme des angles d'un triangle est 180°.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":21373,"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 divisé par 9 donne 5, car 9 × 5 = 45.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":21374,"question":"Vrai ou Faux : Le périmètre d'un rectangle est égal à la somme de ses deux longueurs.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"B","explication":"Le périmètre d'un rectangle est égal à 2 × (longueur + largeur). L'affirmation est donc fausse.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":21375,"question":"Quel est le résultat de 2\/3 × 9 ?","option_a":"4","option_b":"6","option_c":"8","option_d":"12","option_e":"","option_f":"","bonne_reponse":"B","explication":"2\/3 × 9 = (2 × 9) \/ 3 = 18 \/ 3 = 6.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":21376,"question":"Vrai ou Faux : Un angle droit mesure 90°.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Un angle droit mesure bien 90°, c'est une définition fondamentale en géométrie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":21377,"question":"Quel est le résultat de 15% de 80 ?","option_a":"8","option_b":"10","option_c":"12","option_d":"15","option_e":"","option_f":"","bonne_reponse":"C","explication":"15% de 80 = (15\/100) × 80 = 0,15 × 80 = 12.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0}]
