[{"id":192631,"question":"Quel est le résultat de l'opération suivante : 12 × (8 - 3) ?","option_a":"60","option_b":"50","option_c":"45","option_d":"70","option_e":"","option_f":"","bonne_reponse":"a","explication":"Appliquez d'abord la soustraction entre parenthèses (8 - 3 = 5), puis multipliez par 12 (12 × 5 = 60).","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"60\", \"b\": \"50\", \"c\": \"45\", \"d\": \"70\"}}","_debug_options_count":4},{"id":192632,"question":"La division de 45 par 5 donne 9. Vrai ou Faux ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"45 ÷ 5 = 9 est correct. La division est une opération inverse de la multiplication (5 × 9 = 45).","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Vrai\", \"b\": \"Faux\", \"c\": \"\", \"d\": \"\"}}","_debug_options_count":4},{"id":192633,"question":"Quel est le résultat de 3\/4 + 1\/4 ?","option_a":"1","option_b":"4\/4","option_c":"2\/4","option_d":"3\/2","option_e":"","option_f":"","bonne_reponse":"b","explication":"Les fractions ont le même dénominateur (4). Additionnez les numérateurs : 3 + 1 = 4. Le résultat est 4\/4, soit 1.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"1\", \"b\": \"4\/4\", \"c\": \"2\/4\", \"d\": \"3\/2\"}}","_debug_options_count":4},{"id":192634,"question":"Un rectangle a une longueur de 8 cm et une largeur de 5 cm.

Ici, 2 × (8 + 5) = 2 × 13 = 26 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"26 cm\", \"b\": \"40 cm\", \"c\": \"13 cm\", \"d\": \"30 cm\"}}","_debug_options_count":4},{"id":192635,"question":"La multiplication est une opération commutative. Vrai ou Faux ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"La multiplication est commutative, ce qui signifie que a × b = b × a. Par exemple, 3 × 4 = 4 × 3.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Vrai\", \"b\": \"Faux\", \"c\": \"\", \"d\": \"\"}}","_debug_options_count":4},{"id":192636,"question":"Quel est le résultat de 7 × 0 ?","option_a":"0","option_b":"7","option_c":"1","option_d":"70","option_e":"","option_f":"","bonne_reponse":"a","explication":"Tout nombre multiplié par 0 donne 0. C'est une propriété fondamentale de la multiplication.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"0\", \"b\": \"7\", \"c\": \"1\", \"d\": \"70\"}}","_debug_options_count":4},{"id":192637,"question":"Un élève a 15 dinars et dépense 7 dinars. Combien lui reste-t-il ?","option_a":"8 dinars","option_b":"22 dinars","option_c":"12 dinars","option_d":"7 dinars","option_e":"","option_f":"","bonne_reponse":"a","explication":"Pour trouver le reste, soustrayez la dépense de l'argent initial : 15 - 7 = 8 dinars.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"8 dinars\", \"b\": \"22 dinars\", \"c\": \"12 dinars\", \"d\": \"7 dinars\"}}","_debug_options_count":4},{"id":192638,"question":"Pour résoudre un problème, il faut toujours commencer par la dernière opération. Vrai ou Faux ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"b","explication":"Il faut analyser le problème pour déterminer l'ordre des opérations. Commencer par la dernière opération n'est pas toujours la bonne méthode.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"Vrai\", \"b\": \"Faux\", \"c\": \"\", \"d\": \"\"}}","_debug_options_count":4},{"id":192639,"question":"Quel est le résultat de 15 ÷ 3 + 2 ?","option_a":"7","option_b":"6","option_c":"5","option_d":"9","option_e":"","option_f":"","bonne_reponse":"a","explication":"Appliquez d'abord la division (15 ÷ 3 = 5), puis ajoutez 2 (5 + 2 = 7).
