[{"id":17258,"question":"Quel est le résultat de l'opération suivante : 15 + 7 × 2 ?","option_a":"29","option_b":"44","option_c":"22","option_d":"37","option_e":"","option_f":"","bonne_reponse":"A","explication":"La multiplication est prioritaire sur l'addition. Donc 7 × 2 = 14, puis 15 + 14 = 29.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":17259,"question":"L'équation x + 5 = 12 a pour solution x = 7.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"En soustrayant 5 des deux côtés, on obtient x = 12 - 5 = 7. L'affirmation est donc vraie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":17260,"question":"Quel est le résultat de 48 ÷ 6 ?","option_a":"6","option_b":"8","option_c":"7","option_d":"9","option_e":"","option_f":"","bonne_reponse":"B","explication":"48 divisé par 6 donne 8, car 6 × 8 = 48.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":17261,"question":"Le nombre 3,25 est un nombre entier.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"B","explication":"Un nombre entier n'a pas de partie décimale. 3,25 est donc un nombre décimal, pas un entier.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":17262,"question":"Quel est le résultat de (10 - 4) × 3 ?","option_a":"12","option_b":"18","option_c":"24","option_d":"6","option_e":"","option_f":"","bonne_reponse":"B","explication":"Les parenthèses sont prioritaires : 10 - 4 = 6, puis 6 × 3 = 18.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":17263,"question":"L'équation 2x = 14 a pour solution x = 7.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"En divisant les deux côtés par 2, on obtient x = 14 ÷ 2 = 7. L'affirmation est vraie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":17264,"question":"Quel est le résultat de 0,5 × 10 ?","option_a":"5","option_b":"0,5","option_c":"50","option_d":"0,05","option_e":"","option_f":"","bonne_reponse":"A","explication":"0,5 multiplié par 10 donne 5, car déplacer la virgule d'un rang vers la droite équivaut à multiplier par 10.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":17265,"question":"Le nombre 1234 est divisible par 2.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Un nombre est divisible par 2 s'il se termine par 0, 2, 4, 6 ou 8. 1234 se termine par 4, donc il est divisible par 2.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":17266,"question":"Quel est le résultat de 15 - (3 + 2) ?","option_a":"10","option_b":"5","option_c":"12","option_d":"8","option_e":"","option_f":"","bonne_reponse":"A","explication":"Les parenthèses sont prioritaires : 3 + 2 = 5, puis 15 - 5 = 10.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":17267,"question":"L'équation x - 8 = 0 a pour solution x = 8.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"En ajoutant 8 des deux côtés, on obtient x = 8. L'affirmation est donc vraie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0}]
