[{"id":23338,"question":"Quel est le résultat de l'opération suivante : 45 + 27 ?","option_a":"62","option_b":"72","option_c":"52","option_d":"82","option_e":"","option_f":"","bonne_reponse":"B","explication":"45 + 27 = 72. Additionnez les unités (5+7=12), retenez 1, puis additionnez les dizaines (4+2+1=7).","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":23339,"question":"La multiplication est une opération commutative : 5 × 3 = 3 × 5.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Vrai. La multiplication est commutative : l'ordre des facteurs ne change pas le résultat.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":23340,"question":"Quel est le résultat de 120 ÷ 8 ?","option_a":"15","option_b":"12","option_c":"10","option_d":"20","option_e":"","option_f":"","bonne_reponse":"A","explication":"120 ÷ 8 = 15. Divisez 120 par 8 : 8 × 15 = 120.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":23341,"question":"Dans l'opération (3 + 5) × 2, quelle opération doit-on effectuer en premier ?","option_a":"L'addition","option_b":"La multiplication","option_c":"Les deux en même temps","option_d":"La soustraction","option_e":"","option_f":"","bonne_reponse":"A","explication":"Les parenthèses indiquent la priorité : on effectue d'abord l'addition (3 + 5 = 8), puis la multiplication (8 × 2 = 16).","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":23342,"question":"Le nombre 48 est divisible par 6.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Vrai. 48 ÷ 6 = 8, donc 48 est divisible par 6.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":23343,"question":"Quel est le résultat de 7 × (4 + 3) ?","option_a":"49","option_b":"25","option_c":"35","option_d":"14","option_e":"","option_f":"","bonne_reponse":"B","explication":"D'abord, calculez la parenthèse : 4 + 3 = 7. Puis multipliez : 7 × 7 = 49.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":23344,"question":"Un problème demande : 'J'ai 24 bonbons à partager entre 6 amis. Combien chacun reçoit-il ?' Quelle opération faut-il utiliser ?","option_a":"Addition","option_b":"Soustraction","option_c":"Multiplication","option_d":"Division","option_e":"","option_f":"","bonne_reponse":"D","explication":"Il faut diviser 24 bonbons par 6 amis : 24 ÷ 6 = 4 bonbons par ami.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":23345,"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. Par exemple, si 5 × 3 = 15, alors 15 ÷ 3 = 5.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":23346,"question":"Quel est le résultat de 15 − (8 + 2) ?","option_a":"5","option_b":"10","option_c":"7","option_d":"15","option_e":"","option_f":"","bonne_reponse":"A","explication":"D'abord, calculez la parenthèse : 8 + 2 = 10. Puis soustrayez : 15 − 10 = 5.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":23347,"question":"Pour calculer 3 × 4 + 2, quelle opération doit-on effectuer en premier ?","option_a":"La multiplication","option_b":"L'addition","option_c":"Les deux en même temps","option_d":"La soustraction","option_e":"","option_f":"","bonne_reponse":"A","explication":"La multiplication a priorité sur l'addition : 3 × 4 = 12, puis 12 + 2 = 14.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0}]
