Jeremy26i Bonsoir Sia20020919 (beaucoup de chiffres),

a) $\frac{4}{5} + \frac{21}{-35} = \frac{4}{5} - \frac{3}{5} = \frac{1}{5}$

b) $- \frac{8}{12} + \frac{1}{6} = -\frac{4}{6} + \frac{1}{6} = -\frac{3}{6} = -\frac{1}{2}$

c) $\frac{24}{15} + \frac{-16}{20} = \frac{8}{5} - \frac{4}{5} = \frac{4}{5}$

d) $\frac{2}{3} - \frac{30}{18} = \frac{2}{3} - \frac{5}{3} = -\frac{3}{3} =- 1$

e) $- \frac{27}{12} - \frac{5}{4} = -\frac{9}{4} - \frac{5}{4} =- \frac{14}{4} =- \frac{7}{2}$

f) $\frac{48}{30} - \frac{12}{40} = \frac{16}{10} - \frac{3}{10} = \frac{13}{10}$
