Bonjour,
[tex]C = \frac{\frac{4}{7} }{\frac{11}{-14} } \\\\C = \frac{4}{7}*\frac{-14}{11} \\\\C = \frac{-56}{77}\\\\C = \frac{-56:7}{77:7}\\\\C = \frac{-8}{11}[/tex]
[tex]D = \frac{\frac{5}{4} }{10} \\\\D = \frac{5}{4}*\frac{1}{10}\\\\D = \frac{5}{40} \\\\D = \frac{5:5}{40:5}\\\\D = \frac{1}{8}[/tex]
J’espère t’avoir aidé ^^
Bonne journée et bonne continuation.
