[{"id":73322,"question":"Quel est le résultat de 3,5 × 2 ?","option_a":"5,5","option_b":"6,5","option_c":"7","option_d":"7,5","option_e":"","option_f":"","bonne_reponse":"D","explication":"3,5 × 2 = 7. Multiplier un nombre décimal par 2 revient à doubler sa valeur.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":73323,"question":"Un rectangle a une longueur de 8 cm et une largeur de 5 cm. Quel est son périmètre ?","option_a":"13 cm","option_b":"26 cm","option_c":"30 cm","option_d":"40 cm","option_e":"","option_f":"","bonne_reponse":"B","explication":"Le périmètre d'un rectangle se calcule avec la formule P = 2 × (longueur + largeur). Ici, P = 2 × (8 + 5) = 26 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":73324,"question":"Vrai ou Faux ? 0,75 est supérieur à 3\/4.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"B","explication":"0,75 = 3\/4. Les deux valeurs sont égales, donc l'affirmation est fausse.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":73325,"question":"Quelle est la fraction irréductible de 12\/18 ?","option_a":"2\/3","option_b":"4\/6","option_c":"6\/9","option_d":"1\/2","option_e":"","option_f":"","bonne_reponse":"A","explication":"12\/18 se simplifie en divisant le numérateur et le dénominateur par 6 : 12 ÷ 6 = 2 et 18 ÷ 6 = 3, donc 2\/3.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":73326,"question":"Convertis 2,5 kg en grammes.","option_a":"25 g","option_b":"250 g","option_c":"2500 g","option_d":"25000 g","option_e":"","option_f":"","bonne_reponse":"C","explication":"1 kg = 1000 g, donc 2,5 kg = 2,5 × 1000 = 2500 g.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":73327,"question":"Vrai ou Faux ? La somme de deux angles complémentaires est toujours égale à 180°.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"B","explication":"Deux angles complémentaires ont une somme de 90°. La somme de 180° correspond à des angles supplémentaires.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":73328,"question":"Quel est le résultat de 45 ÷ 5 ?","option_a":"8","option_b":"9","option_c":"10","option_d":"11","option_e":"","option_f":"","bonne_reponse":"B","explication":"45 divisé par 5 donne 9, car 5 × 9 = 45.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":73329,"question":"Un triangle isocèle a deux côtés de 6 cm et un côté de 4 cm. Quel est son périmètre ?","option_a":"10 cm","option_b":"16 cm","option_c":"18 cm","option_d":"20 cm","option_e":"","option_f":"","bonne_reponse":"B","explication":"Le périmètre se calcule en additionnant les longueurs des trois côtés : 6 + 6 + 4 = 16 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":73330,"question":"Vrai ou Faux ? 1\/2 + 1\/4 = 3\/4.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Pour additionner des fractions, il faut un dénominateur commun. 1\/2 = 2\/4, donc 2\/4 + 1\/4 = 3\/4. L'affirmation est vraie.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":73331,"question":"Quelle unité utilise-t-on pour mesurer la capacité d'un verre d'eau ?","option_a":"Kilogramme","option_b":"Litre","option_c":"Mètre","option_d":"Centimètre","option_e":"","option_f":"","bonne_reponse":"B","explication":"La capacité se mesure en litres (ou sous-multiples comme le centilitre).","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0}]
