Bonjour,
[tex] \frac{12}{36} = \frac{12\div12}{36\div12} = \frac{1}{3} [/tex]
[tex] \frac{25}{15} = \frac{25\div5}{15\div5} = \frac{5}{3} [/tex]
[tex] \frac{30}{40} = \frac{30\div10}{40\div10} = \frac{3}{4} [/tex]
[tex] \frac{102}{360} = \frac{102\div6}{360\div6} = \frac{17}{60} [/tex]
En espérant t'avoir aidé(e) ! ^^
