[{"id":28548,"question":"Quel est le résultat de 15 × 4 ?","option_a":"50","option_b":"60","option_c":"70","option_d":"80","option_e":"","option_f":"","bonne_reponse":"B","explication":"15 multiplié par 4 donne 60. C'est une multiplication de base à maîtriser.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":28549,"question":"La fraction 3\/4 est-elle équivalente à 6\/8 ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Oui, car 3\/4 = (3×2)\/(4×2) = 6\/8. Les fractions équivalentes représentent la même valeur.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":28550,"question":"Quel est le résultat de 125 ÷ 5 ?","option_a":"20","option_b":"25","option_c":"30","option_d":"35","option_e":"","option_f":"","bonne_reponse":"B","explication":"125 divisé par 5 donne 25. Une division simple à connaître par cœur.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":28551,"question":"La somme de 2\/3 et 1\/6 est-elle égale à 5\/6 ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Oui, car 2\/3 = 4\/6 et 4\/6 + 1\/6 = 5\/6. Il faut mettre les fractions au même dénominateur.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":28552,"question":"Quel est le résultat de 7 × (8 + 2) ?","option_a":"70","option_b":"80","option_c":"90","option_d":"100","option_e":"","option_f":"","bonne_reponse":"B","explication":"D'abord, on calcule la parenthèse : 8 + 2 = 10. Ensuite, 7 × 10 = 70. Respecter l'ordre des opérations est crucial.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":28553,"question":"La fraction 5\/10 est-elle simplifiable en 1\/2 ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Oui, car 5\/10 = (5÷5)\/(10÷5) = 1\/2. Simplifier une fraction consiste à diviser le numérateur et le dénominateur par leur PGCD.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":28554,"question":"Quel est le résultat de 100 - 47 ?","option_a":"43","option_b":"53","option_c":"63","option_d":"73","option_e":"","option_f":"","bonne_reponse":"B","explication":"100 moins 47 donne 53. Une soustraction de base à maîtriser pour les calculs mentaux.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":28555,"question":"La division de 1\/2 par 2 donne-t-elle 1\/4 ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Oui, car diviser par 2 revient à multiplier par 1\/2. Donc (1\/2) × (1\/2) = 1\/4.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":28556,"question":"Quel est le résultat de (15 + 5) × 2 ?","option_a":"30","option_b":"40","option_c":"50","option_d":"60","option_e":"","option_f":"","bonne_reponse":"B","explication":"D'abord, on calcule la parenthèse : 15 + 5 = 20. Ensuite, 20 × 2 = 40. L'ordre des opérations est essentiel.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":28557,"question":"La fraction 8\/12 est-elle simplifiable en 2\/3 ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Oui, car 8\/12 = (8÷4)\/(12÷4) = 2\/3. Simplifier une fraction facilite les calculs ultérieurs.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0}]
