Réponse :
[tex]A = \frac{4}{3}-\frac{5}{12} \\A = \frac{16}{12} -\frac{5}{12} \\\\A = \frac{11}{12}[/tex]
[tex]B = \frac{-5}{4} \times \frac{2}{11} \\B = \frac{-5 \times 2}{2 \times 2 \times 11} \\B = \frac{-5}{2 \times 11} \\B = \frac{-5}{22}[/tex]
[tex]C=\frac{5}{14} :\frac{3}{4} \\C=\frac{5}{14} \times \frac{4}{3} \\\\C=\frac{5 \times 2 \times 2}{2 \times 7 \times 3} \\\\C = \frac{5 \times 2 }{ 7 \times 3} \\\\C = \frac{10}{21}[/tex]
[tex]D = \frac{1}{3} +\frac{5}{3} \times \frac{-7}{4} \\D = \frac{1}{3} + \frac{-35}{12} \\D= \frac{4}{12} - \frac{35}{12} \\D = -\frac{31}{12}[/tex]
