x22 Bonsoir,

$\frac{2}{5} - \frac{1}{3} : \frac{2}{5} + \frac{1}{3} = \frac{2*3}{5*3} - \frac{1*5}{5*3} :\frac{2}{5} + \frac{1}{3} = \frac{6}{15} - \frac{5}{15} : \frac{2*3}{5*3} + \frac{1*5}{3*5} =$
= $\frac{6}{15}- \frac{5}{15} }: \frac{6}{15} + \frac{5}{15}= \frac{1}{15} : \frac{11}{15} = \frac{1}{11}$

Voilà
